SoundOff Signal's Alternating DRL Flasheris a Solid State design flasher with Daytime Running Lights. At night the flasher allows the low beam headlights to remain ON while the high beams flash to gain attention and increase visibility. When the vehicles high beams are turned on, the flasher sequence stops for normal high beam function. Any time the vehicle is running, the flasher system will activate the high beam headlight into a daytime running mode and turn on the side marker lights. Five year No Hassle Warranty.
