The Flashback Five’s advanced LED light and reflector technology makes it the brightest and most powerful signal light available. Its five stage switch provides red, blue, red/blue alternating, red/blue blend and a flashlight selection. The 20 brilliant LED bulbs can be seen for up to 1 mile and provides 300 hours of continuous flashing! The Flashback Five™ can be used as a signal light, a vehicle warning light (with its built in magnetic mount tailcap – placement can be anywhere on vehicle) or as an “on-the-scene” dash or deck light.
