The LED Cop Strobes are powerful and professional grade strobes. Each bulb emits more than 300 lm of light. The strobes use a new type of LED that is big and flat. Their aluminum base with a specially designed bulb to allow light to be emitted in all directions take maximum advantage of the vehicle's headlight reflectors. They are programmed with 5 different flashing strobe sequences that are controlled by a dome-cap micro-controller.
