This low-profile fuel gauge replaces the analog readout with bright LED lamps. The six edge-mounted LED lamps glow blue when the tank is full and extinguish one by one as fuel is consumed. Plug-in installation without splicing. Photocell automatically adjusts LED brightness for improved visibility in direct sunlight and dims at night to avoid distraction. Fits '09-'17 Dyna (except FXD), '08-'17 Softail (except FLSTNSE, FXCW, FXCWC, FXS, FXSB, FXSBSE and FXSE). '08-'17 Road King and '15-'17 Freewheeler models.
