38.5 Inch warning strobe light bar comes with 80 high intensity LEDS which are brighter and more effective than standard LED Strobe Lights. Both the front and back of the light have 6 groups of LEDs, and both left and right sides one. This unique design not only meets higher brightness needs but also warns other vehicles more effectively. The Amber/White combination will attract the attention of others more, and it could be seen easily in the rain, fog, dust, and snow weather to warn other vehicles.
