What is a LED Light Bar and Why Do You Need One?



A light bar is a short or long array of high-luminosity LED lights. These supplement your vehicle’s stock headlamps. They provide a brighter, broader and penetrating beam of light ahead, behind or to the side. They provide a significant advantage for night driving or when illuminating trails, campsites or work areas.

Light Bar Applications

  • Night Driving – Light bars can produce a dramatic difference in road visibility over the brightest stock headlights. By the way, you can check LED headlights for Jeep Wrangler. Those are not so powerful as light bars, but better than stock headlights!
  • Emergency Lighting – A light bar is indispensable for lighting accident or breakdown scenes. Their brightness also alerts other drivers to trouble ahead.
  • Backyards – A light bar will illuminate an entire yard for parties or cleanup activities. They make an excellent prowler deterrent.
  • Boats – For increasing marine visibility and lighting landing sites or docks, light bars are ideal.
  • Heavy equipment – Snow plows, graders and tractors find light bars essential in poorly lighted conditions.
  • Off-Road – When taking your 4WD or ATV into the backcountry, a light bar is a must-have for hazard spotting or setting up campsites.

Different Types of Lamps

These are the most common automotive and commercial high intensity lamps:

  • Tungsten-Vacuum Lights – A tungsten wire filament within a vacuum is heated by electricity causing the wire to emit light.
  • Halogen Lights – A high-performance version of Tungsten-Vacuum lamps with a tungsten filament enclosed in halogen or iodine gas.
  • HPS Lamps – High-Pressure and Low-Pressure Sodium lamps pass an electric arc through a gas mixture containing mostly sodium.
  • HID Lamps – High Intensity Discharge lamps pass an electric arc through gas mixtures that also contain metal salts to form a high intensity plasma.
  • LED Lamps – Light-Emitting Diodes are solid state devices that emit light when electrons pass to electron holes. Manufacturers double their efficiency about every 3 years.



Ordinary vacuum filament lamps were standard for cars from the 1930s until the 1990s, until more efficient lamps were developed. They are still used in directional signals and license plate lamps.

Pros / Cons

  •  Inexpensive to manufacture
  • Low ratio of lumens to power
  • Require high output electrical generators
  • Filaments boiling off darken bulb
  • Short life span


Halogen, or quartz-halogen, headlamps are the most common type of lamp found on cars today. They achieve a higher filament temperature than ordinary bulbs. They save fuel and manufacturing costs since wires, switches, and alternators can be smaller.

Pros / Cons

  • Relatively low cost
  • Lifespan over 1000 hours
  • Increased efficiency
  • Waste significant power as heat


High-pressure sodium lamps are commonly used for street lighting. They are highly efficient because nearly all the light produced is within the human visual spectrum. Most lamps augment the sodium with mercury and use neon or argon for faster starting.

Pros / Cons

  • High efficiency
  • Long life
  • Narrow spectrum, unnatural light
  • Start-up time over 5 minutes
  • Mercury is highly toxic


High-Intensity Discharge lamps improve on halogen lamps both in efficiency and life. Adjusting the mix of gas and salts produces different color temperatures. Since all the mixtures contain xenon gas, they are often referred to as xenon lamps. The xenon gas eliminates start-up flicker.

Pros / Cons

  • Twice as efficient as halogen lamps
  • Lifespan over 2000 hours
  • Wide choice of color
  • Better directivity
  • Dirty lenses produce glare for oncoming drivers
  • Rare earth elements are costly
  • Require a DC-DC converter for a higher operating voltage



LEDs became practical for road illumination relatively recently but are now a highly efficient automotive lighting option. Modern cars use them extensively for road lights, direction signals and interior lighting.

Pros / Cons

  • Up to 80 percent efficiency in light output
  • Lifespan over 50,000 hours
  • Widest color spectrum
  • Enable millisecond adjustments in light beams
  • Expensive, but prices trending lower
  • Require temperature compensation

Why We Recommend LEDs for Light Bars

If you can pardon the pun, LED lighting outshines its competition in many ways except for initial cost. For road and outdoor lighting, it offers long life and efficient light production, but there are additional advantages.

Type Lifespan Hrs. Eff. lm/W Color Temp Color Render Notes
Tungsten-Vacuum 750-1000 6-20 2700 100 Cheap
Halogen 1000-2000 20-35 3000 100 Run hot
HPS >10000 65-140 1800-2500 20-30 Needs ballast
HID 2000-4000 80-125 2700-5600 60-70 DC converter
LED >20000 20-160 1100-9000 20-95 Higher initial cost

What the Table above Measures

  • The efficiency of a particular lamp technology is measured in lumens per watt, which tells you how much light you get for a given amount of electricity.
  • Color temperature specifies where in the human visible light spectrum the light falls. A lower number indicates a warmer, yellowish light, whereas higher temperature produces a whiter or bluish light.
  • Color render refers to the ability of a lamp to recreate natural colors at night.

As the table above demonstrates, LEDs, despite higher initial cost, are most cost-effective over their lifetime. They compare well in efficiency with HID lights and, depending on the color temperature chosen, can create nearly perfect rendering of colors. For better understanding, see some comparisons of light bulbs in household.

Other Advantages of LED Lights

  • Instead of depending on a single bulb, a headlight or light bar consists of separate high-intensity lamps, which increases reliability.
  • LEDs do not require a ballast or voltage conversion, since they run well at the normal 13.8 volts of most automotive systems. You can run them from portable generators too.
  • They project their heat rearward, so the lenses are cool to the touch.
  • LED headlamps and light bars, unlike filament lamps, stand up well to vibration and shocks.

LED Light Bar Applications

LED Light Bars for TrucksLED Light Bars for Trucks

A truck LED light bar is an important accessory whether you use your truck for pleasure, work or both. A light bar mounted across the cab is perfect for illuminating any road on dark nights or lighting up a construction site past sunset.Mount one on the tailgate for a super bright backup light. A red LED brake light bar significantly increases your visibility to drivers behind you.

Off-Road LED Light BarsOff-Road LED Light Bars

The best off-road lights brighten the terrain ahead, but must be rugged enough to withstand the bumps and shocks of the trail. LED light bars are ideal, since the lamps are solid-state.

See the LED light bar reviews later in this guide to compare build quality and their ability to resist dust and water penetration.

ATV LED Light BarsATV LED Light Bars

Two short ATV light bars front and back improve your vehicle’s visibility during darkness or daytime, especially on sunken trails or in dunes. It gives you excellent output when it comes to brightness and light-weight intensity.

You can augment these with red strobe LED light bars mounted high on your equipment.

ATV LED light bars draw so little current that you can leave them on when trailering for extra safety.

LED Light Bars for Other VehiclesLED Light Bars for Other Vehicles

Whenever you need to see your surroundings or be seen, one or more LED light bars makes a big difference. A pair of auxiliary LED amber lamps mounted low will penetrate fog, drizzle and the gloom ahead. An LED light bar in your trunk, under the engine hood or the car interior lights up every nook and cranny. An LED brake light bar increases reliability over standard brake lights. Motorcycles and golf carts become safely conspicuous with the addition of strategically placed red, blue or amber LED light bars.

Emergency LED Light BarsEmergency LED Light Bars

High luminosity and low power consumption make LED emergency lights essential for fire trucks, ambulances, police cars and other public service vehicles. Emergency LED lights fit in vehicle grills, sun visors, mirrors or on the roof. Choose white, yellow, red, blue or a mix to maximize visibility. Their millisecond on-off cycle time makes them ideal for flashing or strobe applications that alert drivers and pedestrians. Bright white LED light bars will flood incident areas with light.

LED Work Light BarsLED Work Light Bars

A long, curved LED light bar producing 24,000 effective lumens will consume less than 300 watts and draw 22 amps, which is less than most headlight systems. It can flood a large work site with bright light. Smaller light bars on a truck rack can provide spot lighting or illuminate a truck bed.

Add a backup battery or generator, and they are completely portable.

Marine LED Light BarsMarine LED Light Bars

High-quality marine LED light bars are waterproof and come in a variety of colors. They make excellent navigation lights. White or amber light bars will light up landing sites or dock approaches. Small light bars are great for illuminating controls, hatches or an engine compartment. Their input voltage range is a good match for most marine electrical systems.

LED Strobe Light BarsLED Strobe Light Bars

LED strobe lights can be white, red, amber, blue or green, any of which can draw attention to potential hazards. Light flashes can be regular or irregular to alert workers to out-of-spec operating conditions. Rotating beacons are simulated by electronic sequential switching. Their low power consumption is suited for portable traffic control and construction warning signs.

Interior LED Light BarsInterior LED Light Bars

LED light bars can bathe an outdoor patio or a garage in bright light. Smaller light bars can illuminate workbenches, crawlspaces or attics. Thanks to a greater ability to focus and direct light, we find that the LED light bar create better visibility for the owner. They run from a 12 volt battery or a portable generator, so make reliable backup lighting during power outages.

LED Mini Light BarsLED Mini Light Bars

Portable, mini light bars can plug directly into an automotive 12VDC outlet for hazard or interior lighting. They work well for under-cabinet lighting or to brighten a dark closet. They are often used for outdoor lighting accents around ponds or landscaping. These can be supplied with power from a small solar panel and sealed lead-acid batteries.

LED Light Bar Types

LED light bars may contain one LED or dozens. The LEDs within a single bar are usually the same size but power sizes and colors can be mixed. For example, a police vehicle light bar may contain white, amber, red and blue LEDs of various strengths. Some or all of these may flash.

Mini Light Bars

Mini Light Bars

The smallest light bars are often referred to as light pods. They are used as side lights, work lights or portable spotlights. Cubes of 4 LEDs are regularly used as fog lamps.

Full-size Light Bars

Full-size Light BarsThese are rectangular, enclosed arrays of up to 96 LEDs in a single bar. The LEDs may be arranged in single, double or quad rows.

The best LED light bar used for road or job site illumination has LEDs with a color temperature of 5000K, which simulates sunlight on a clear day. Custom reflectors or lenses spread, focus or diffuse the beam. Two or more beam angles are created in combo bars.

Low-Profile Light Bars

These light bars contain a single row of LEDs and are usually under 20 inches long. Their low profile makes them ideal for vehicle grill mounting.

Colored LED Light BarsColored LED Light Bars

The range of colors available for LEDs runs from deep red to hot blue. There are even LEDs that emit UV and IR light, which often find application at your dentist’s office or for trail cams, respectively.

Cree LED Light BarWhat Is a Cree LED Light Bar?

In your search for the best LED light bar, you will come across the term Cree light bar. Cree refers to the LEDs in the light bar, not to the brand of light bar. All the light bars in this guide’s LED light bar reviews use a version of Cree LEDs.

led-distanceCree, Inc., located in North Carolina, manufactures these powerful, highly efficient LEDs. They are the highest quality, longest lasting, and most efficient LED lighting for homes, businesses and roadways.

The finest Cree LED light bars have an efficiency at the top end of the scale for LEDs approaching 120 raw lm/W. With proper current control, they have a lifespan over 50,000 hours. Unlike cheaply made LEDs, Cree LEDs do not fade early. Despite higher initial cost compared to other LEDs, in the long run they cost less to operate.

As an example, a popular light bar choice is a 20″ Cree LED light bar that contains 40 3-WCree LEDs. This runs at 120 watts and produces 9600 effective lumens.

Flood, Spot or Combo – Which LED Light Bar Do I Need?

led-anglesUnlike standard screw-in home bulbs, which throw light out in all directions, LED light bars concentrate their light in one direction.

The way the light beam is formed depends on each LED’s reflector and the shape of the lens. Modern light bars use computer-aided designs to achieve specific lighting patterns.

The lighting pattern trade-off for light bars is between distance and beam width. For the same luminosity, more distance requires less beam width and vice versa. When a design favors a wider beam width, you have a flood light. More distance is achieved by narrowing the light beam into a spot pattern.

spot-flood-comboA flood LED light bar typically has between 40 and 120 degrees of beam width. Spots are around 10 to 30 degrees. Keep in mind that flood and spot degrees vary between different models of led light bars.

So which one is best? It depends on the application. Both are useful and a common choice is to buy one of each or purchase a combo bar that has spot and flood functions combined.

A combo works by assigning the jobs of the spot and the flood light to different sections of the light bar. It can do this by dividing flood and spot reflectors along the bar’s length or by splitting the functions between rows. The best LED light bar of one manufacturer allows you to custom design your flood to spot ratio with swappable reflectors.

Factors to Consider When Evaluating the Best LED Light Bar

LengthLight Bar Length

Enclosed LED light bars typically come in the following lengths: 4 inch led light pod, 6 inch led light bar, 10 inch led light bar, 20 inch led light bar, 24 inch led light bar, 30 inch led light bar, 36 inch led light bar, 40 inch led light bar, 50 inch led light bar.


Light bars can be round, rectangular or square. Round ones are able to fit more LEDs in a smaller area and may complement your vehicle’s design better than square lights.

Beam-AngleBeam Angle

As discussed previously, the beam angle dictates the width and depth of the area of illumination. For driving, deeper penetration is usually better and to light up work sites a wide angle works well.

ConnectorsElectrical Connectors

Two types of waterproof connectors are used on quality LED light bars, which are referred to as ATP or DT connectors. Both types are made from thermoplastic and have IP ratings of IP67 or above. They operate within a wide temperature range and use corrosion-resistant contacts and silicone seals. They accommodate several wire sizes.


Lumens per watt, or lm/W, measures the efficiency of a single LED or an entire LED light bar. This is a good, though not perfect, indicator as to the quality of the LEDs in the light bar. Higher efficiency LEDs have a longer life and resist fading. Manufacturers can fudge this number by measuring lumens at a voltage lower than the normal 13.8 VDC found in most vehicles.


For LED light bars, brightness is expressed in lumens. Measuring lamps in watts became obsolete when different lighting technologies came to market. The lumen indicates how much human visible light a device outputs. However, some light bar makers list their lights in raw lumens, which is the theoretical maximum, instead of effective lumens, which is a true measure of light output. A rule of thumb is to convert raw lumens to effective lumens by multiplying the former by 0.8.

TemperatureLED Color Temperature

Correlated Color Temperature, or CCT, specifies where a lamp’s output falls in the visible light spectrum. The unit of measurement is on the Kelvin temperature scale. Thus, a particular lamp’s temperature is a number followed by a K, such as 5000K.

Cooler light temperatures are at the red end of the spectrum but are perceived by humans as “warm,” whereas higher temperatures are seen as “cool.” LEDs can produce light all over this scale, from about 1000K to 9000K, but only a small range is useful for an LED light bar.

Since the sun on a clear day produces light in the range of 5000K to 5400K, that range is excellent for night driving because human eyes evolved to work well in that range. Above that, around 6000K, the light may appear brighter, but your eyes work harder to recognize terrain, which induces eye fatigue. However, LEDs running at higher CCT are more energy efficient than at lower color temperatures.

Color temperatures in the yellow part of the spectrum are ideal for fog lights because of significantly reduced backscatter from the water droplets. Other temperatures that produce blue, amber, red or green are important for LED lights being used for alert signals.

ResistanceWater and Dust Resistance

Manufacturers have adopted an IEC standard known as the IP Code, where IP stands for Ingress Protection. Good LED light bars carry an IP rating to indicate resistance to dust and water entering the light.

All you need to be concerned with regarding IP ratings are two numbers. The first, on a scale of 0 to 6, indicates the light bar’s resistance to dust penetration and the second number indicates resistance to water intrusion on a scale of 0 to 8, plus a special 9K rating. You see these numbers preceded by “IP.” For example, a light bar may have a rating of IP67, meaning it is completely sealed against dust and can stand immersion in one meter of water for 30 minutes.

These are typical IP ratings found on LED light bars:

  • IP65 – dust tight and protected against water projected from a nozzle
  • IP66 – dust tight and protected against heavy seas or powerful jets of water
  • IP67 – dust tight and protected against immersion
  • IP68 – dust tight and protected against continuous submersion in water
  • IP69K – dust tight and protected against high temperature, close-range, high pressure spray

VoltageLight Bar Operating Voltage

Most, not all, LED light bars are made to run within the 13.8 DC voltage supplied by most cars or trucks without modification to the light bar or your vehicle’s electrical system.

For instance, it is common to see “9–30 VDC” or “10-70 VDC” as the bar’s input voltage range. These mean that you can operate the LEDs in a 12V, 24V or 48V system as long as that voltage falls within the specified range for the light bar.

LED-DriversLED Drivers

Do not get the idea that if you apply more voltage that the LEDs should give off more light. The amount of light an LED gives off is determined by current, not voltage. The current at each LED is maintained within a narrow range by a device known as an LED Driver.

Without an LED driver, your light bar’s color temperature and brightness would vary considerably. Sometimes, you see in LED light bar reviews owners who apply higher voltage to brighten their lights. Unfortunately, this is an indication that cheap LED drivers were used and this will shorten light bar lifespan.

PWM DriversPWM Drivers

The most sophisticated LED light bars have LED drivers that use Pulse Width Modulation to control LED current. There are also available external PWM units that effectively do the same thing for LED light bars without built-in PWM.

A PWM adjusts the energy frequency applied to the LED. It turns the LED off and on at a high, controlled rate within milliseconds. The rate is well above what the human eye can detect, so there is no flickering effect. This technology offers several benefits:

  • LEDs do not overheat even at 100 percent capacity.
  • LED lifespan is increased.
  • With an external control, you can dim or strobe the light bar.
  • The amperage draw is reduced overall
  • It adds protection against voltage spikes from vehicle electrical systems.

FeaturesOther Features

There are additional features you should keep in mind when evaluating LED light bar products:

  • Warranty – Warranty length and terms help you gauge the confidence a manufacturer has in their product.
  • LED Arrangement – LEDs may be arranged with a single, double or quad row pattern. Multi-row bars often have both spot and flood function.
  • Wiring Harness – The best LED light bar comes with a wiring harness that includes cables, fuse holder, one or more switches and a relay.
  • Multiple Circuits – Some light bars separately switch banks of LEDs for spot or flood. They may include amber, red or blue LEDs on a separate circuit.
  • Color Lenses – Snap-on colored lenses change the light bar’s color.
  • Multi-position Brackets – Some light bars come with optional brackets or a system of brackets that clamp to channels on the light bar housing.

How to Distinguish a Quality LED Light Bar from Cheap Ones

With so many manufacturers of LED light bars, evaluating your options can be confusing. Hopefully, through reading this guide, you will come to understand the various electronic, mechanical and operating features common to most light bars. The next question is how to determine which LED light bars will give you the best service over their lifetime.

The following characteristics may be difficult to discern if you cannot physically handle a light bar, but often LED light bar reviews from owners can help determine them:

  • The number one enemy of LEDs is heat. A quality light bar will have oversize heat sinks and tight current control.
  • If possible, check the operation of a light bar you are considering under different voltage inputs. If the LEDs brighten noticeably as voltage rises, this is a sign of poor LED drivers.
  • Look closely at mounting points and brackets. The best LED light bar has sturdy, corrosion-proof mounting hardware and provide options for mounting the bar in different locations.
  • Check the IP rating. At a minimum, it must be IP65. IP69K is the highest rating, but few light bars achieve that. Make sure the electrical connectors are IP-rated.
  • A wide product line from 3″ light pods up to 50″ bars and plenty of accessories are signs of a quality light bar manufacturer.
  • Most importantly, check the warranty. Top LED light bar makers back their products with lifetime or near-lifetime guarantees. Be sure to check the fine print for exclusions.

Tips on Choosing the Best LED Light Bar

Obviously, LED light bars are not created equally. Their differences include available options, brightness, light color, beam width, heat management, and mounting technology, just to name a few. To reduce potential confusion, start with determining your specific light bar needs.

How Much Light Do You Need?

Most 20″ LED light bars provide more than enough light for good or inclement weather when driving on paved roads. Consider starting with a couple of low-mounted 4″ or 6″ floodlight bars, which will dramatically increase road visibility. If you do a lot of off-road night driving, then larger light bars, up to 50 inches, are useful.

Mounting Options

On most cars, your mounting options are somewhat limited, so low-profile light bars make sense especially for grill mounting. Trucks can mount light bars on the roof, rack, hood or grill, so size and profile are less important.

How to Wire LED Light Bars?

Here are a few important tips on how to wire your LED light bar yourself:

  • First, disconnect your vehicle’s or equipment’s battery. Remove the negative/ground clamp first to avoid shorting to the vehicle’s chassis.
  • Use automotive grade wire designated as GPT, GXL or TXL. GPT is the most common.
  • Use the correct wire gauge. Too large a gauge wastes money but an AWG too small risks overheating the wire, which might lead to a panic-inducing fire. Google a gauge-to-amperes table, which includes how many feet you can run before you need a thicker wire.
  • For big draw light bars, you need large gauge wires, e.g., 6 or 8 AWG. To avoid long runs of thick cable, use a relay between battery and switch. Then you can run lighter gauge to the relay and heavier wires from there to the light.
  • Keep wire lengths short as possible and utilize standard wire colors: black for negative, red for positive and yellow from a relay to a switch.

Judging Quality

It is true that you could buy 2 or more less expensive light bars for the price of a quality one. However, do you really want to risk light bar failure when you need it the most? Reliability and performance come at a cost.

That said, you can make a rough assessment of a manufacturer’s or distributor’s product quality by looking at three things:

  • Length of warranty and warranty terms
  • The breadth of their product line including accessories
  • Reviews from people who actually use their products

Where Can I Buy an LED Light Bar?

There is probably no better way to make a personal assessment of LED light bars than to get your hands on several of them and judge for yourself their build quality and performance attributes. Do this by visiting local shops that carry the brands in which you are interested. Most shops have cutaway demo models so you can examine the insides, especially the heat sink and current limiting technology.

Before you buy a light bar at your local shop, however, be sure to check the manufacturer’s web site or online outlets such as Amazon or large automotive accessory distributors. These often have specials or large discounts that local shops cannot meet.

LED Light Bar FAQ

Should I Use a Relay with My LED Light Bar?
If your LED light bar came with a wiring harness that includes a relay, then the simple answer is “Yes.” Otherwise, it depends. The purpose of the relay is to reduce the current load on the switch. If the switch’s current rating is more than the current draw of the light bar, then directly wiring to the switch is fine. However, give yourself some leeway by using a switch whose amp rating is 50 percent higher than that of the LED light bar. See our LED wiring guide, to see some in depth info regarding wiring.
Can I Run My Light Bar at a Higher Voltage to Make Them Brighter?
First, never apply AC voltage or exceed the DC voltage range specified for your light bar. LED light bars are designed to operate within a specific DC voltage range. They limit the amperage draw to a narrow current range in order to manage the heat and life of each LED. So, a higher voltage should not brighten your light bar. If it does, then probably the LED drivers are of poor design.
My Newly Installed Light Bar Does Not Light Up. What Should I Do?
Failure for a new light to turn on is usually caused by one of four things: a bad switch, a bad relay, wire that is too small or a bad ground connection. If you can connect the light bar directly to the car battery and it lights up, then the failure is due to one of those four conditions.
