Running Mode: Your taillight & turn signals are all illuminated RED. Turn Signal Activated : A flashing amber arrow appears on the appropriate side of the taillight & the selected turn signal flashes amber. Brake Activated : Three-pulse flashes & then your taillight & turn signals remain brightly lit RED until the brake is released. Amber arrow & turn signal will continue to flash during braking function. WHY use panacea rear turn signal inserts? L.E.D. Silver Bullets, stock turn signals, or other custom single filament lights can be used with the Panacea Taillight System but they will function as turn signals only. The Panacea Taillight will retain all of its functions (run, pulse brake, & amber directional arrow). To Realize the Full Benefit of Two-Color, Multi-Function Turn Signals Made Possible by the Panacea System, You Must Use Panacea Rear Turn Signal Inserts. IMPORTANT INFORMATION ABOUT PANACEA TAILLIGHTS: 1. All wiring for trailer lights must be spliced into the wiring harness ahead of the Panacea control module. 2. If the rear of the motorcycle is equipped with any incandescent lights that were not original equipment, such lights must be spliced into the wiring harness ahead of the Panacea control module. Police Models are often equipped with additional lights not found on their civilian counterparts. Be aware that these lights must be rewired, removed, or converted to L.E.D. prior to installing a Panacea system. 3. The Panacea Taillight System meets FMVSS #108 when operated in DOT Mode . There is no provision in FMVSS #108 for flashing brake or amber arrows so those features are disabled when operated in DOT Mode . 4. Panacea Taillights can be used on 97- 01 Dynas, 96- 01 Fat Boy & FXST (except Deuce), & 99- 01 XL Models, but they must be used with stock turn signals. Panacea Turn Signals are not available for these applications.
