- 1. FLASHING STROBE BRAKE LIGHT The 8900T6 tail light includes a built-in flashing brake light to enhance safety. It connects directly to your Harley Davidson motorcycle and requires no programming or wiring for the flashing brake light function. When you brake, the light flashes three times and then remains a bright red. - 2. READY TO INSTALL The LED tail light is ready to install right out of the box. The harness plugs directly into your Harley Davidson motorcycle's harness and includes running light and flashing brake light. No load resistors are required for installing the brake light. The 8900TL6 is compatible with the Harley Davidson on board computer. - 3. DIRECT REPLACEMENT Designed to directly replace the stock rear tail lamp on many Harley Davidson motorcycles. Fits all 1999 or newer Harley Davidson models equipped with an OEM Squareback Tail Light. - 4. QUALITY AND PERFORMANCE An upgrade built to last with an ABS housing and a polycarbonate lens, featuring 136 high-intensity LEDs. Provides a very bright running and brake light and improves visibility, helping you be seen from up to three times farther away. - 5. USE SCENARIOS - Night rides on poorly lit roads benefit from increased conspicuity during braking and overall visibility. - City commuting in heavy traffic where enhanced tail light and brake signaling improve safety for nearby drivers. - Group rides or highway travel where clear, fast-braking signals help maintain safe spacing with other riders and vehicles.
