Whelen LED Light Bar Review

by Simon Wells

Most of the individual light bar products mentioned in this Whelen LED light bar review are specifically made to fit a wide range of American-made cars, trucks and SUVs as well as heavy equipment. Their products are not universally-sized, generic products, so you can expect that their fit and utility are outstanding for the vehicle for which they were designed.

Whelen LED Light Bars

Whelen’s light bar market segments are significantly more demanding than those of other manufacturers whose main requirement is simply illumination of roads, trails and work sites. Like such manufacturers, Whelen’s products are exposed to extreme weather and operating conditions, but they must also grab the attention of drivers and pedestrians in oftentimes hazardous circumstances.

Operational Requirements

  • Bright enough to provide superb visibility even during daylight
  • Low profiles for stealth, aerodynamics and clearance
  • Front and rear facing mounting positions
  • Warning and illumination with open doors or hatches
  • Dynamic selection of colors, intensity and flash patterns
  • Modularity and flexibility to support any operation
  • Detachable light heads, known as “take-downs” or alley lights
  • Low-current requirements and high illumination efficiency
  • Housings that take hard knocks and are resistant to harsh weather and chemical exposure

Whelen Light Bar Key Features

As a result of the aforementioned demands, Whelen has developed over a dozen specific light bar product lines. Although each has its unique benefits, key features are shared across lines:

  • Super low profiles that are almost undetectable and increase inside visibility while reducing driver and passenger flashback.
  • Modular light bar design for flexibility in size and light configuration. Light bars are made of multiple “light heads”, each of which can be switched and programmed independently.
  • Interchangeable lenses for different base color patterns.
  • Light heads in blue, red, amber, white, green or purple.
  • Color and flash patterns configurable via an external ECM and PC software.
  • Ability to alternate or combine flash patterns within a single bar.
  • 100 percent solid-state rotatable beams without moving parts.
  • Heavy duty powder-coated extruded aluminum housings.


What Buyers Are Saying

A Whelen LED light bar review is rarely less than 5 stars. Even many 3 and 4-star reviews contain no complaints. Buyers are impressed with the quality of the construction, operation and especially the brightness.

DOT and tow truck operators say the brightness of the Whelen light bars clears traffic ahead better than any previous light bar they have used. Tow operators appreciate the ability to switch off forward lights at accident or DWI scenes so they do not back light police at the scene.

A few have found the color and flash pattern programming a small hurdle to overcome. Some thought that HID take-downs are better than LEDs in some situations. Everyone seems pleased with the reasonable pricing of Whelen light bars.
