Dynamic Lower Fairing Inserts are a direct replacement for the Harley-Davidson lower fairing radiator grills or filler plates. With more than 130 White & Amber LEDs per side, the inserts produce a bright white running light with amber turn signal that is virtually invisible when off. When the turn signal is activated the white DRL running light turns completely off providing greater visibility to the amber turn signal. Unit simply snaps in place with plug and play wiring for easy installation. Lifetime LED Warranty.
