Finding the Best LED Strobe Light Bars

LED Strobe Light Bar Features

Strobe LED light bars are the first choice in alert lighting for police cars, fire trucks, ambulances, rescue vehicles, highway construction equipment and roadside assistance trucks. They offer conspicuous, head-turning brightness and significant advantages over competing technologies.


Strobe LED light bars use dozens of LEDs and multiple light heads along with programmable controllers. They provide any type of flash/strobe pattern imaginable. The LEDs may be white, blue, red, amber, green or purple to further enhance visibility.

Directional traffic alerts, rotating beacons, heart-stopping strobes, and blinding takedowns are all possible with unlimited lamp arrangements to suit any purpose.


Quality LEDs have lifespans of 50,000 hours. Because dozens of LEDs make up a light bar, redundancy is built in. In the best LED strobe light bar, current draw is tightly controlled over a wide voltage range, so the light bar works equally well with 12V or 24V battery systems.
