Dynamic Lower Fairing Insets are a direct replacement for the H-D lower fairing radiator grills or filler plates. With more than 130 white and amber LEDs per side the inserts produce a bright white running light with amber turn signal that is basically invisible when off. When the turn signal is activated the white DRL running light turns completely off allowing for stronger visibility to the amber turn signal.; ; White running lights Amber turn signals Chip on board LED technology Snap in place Plug and play Lifetime LED warranty
