For the first time, US model rear 1157 turn signals can be upgraded to increase visibility with eye-catching Dual Color LEDs on 2014-2023 Harley-Davidson® Street Glide (FLHX), Street Glide Special (FLHXS), 2015-2023 Road Glide (FLTRX), Road Glide Special (FLTRXS) and 2017-2025 Road King Special (FLHRXS). Using a patent pending technology, these plug and play LED clusters offer 48 LEDs which illuminate Red as a running and brake light, then switch to blink Amber as a full-contrast turn signal. Units are DOT/SAE compliant and include smoked turn signal lenses with watertight gaskets.
Required SMART Turn Signal module is included with plug and play installation under the seat and applies choice of 10 optional brake flash/strobe patterns to the LED turn signals and ProBEAM® LED Run/Brake TriBar (sold separately). Brake pattern can also be applied to any additional Dual Color or Sequential (4 wire) Custom Dynamics® rear lighting product installed on the motorcycle.
Note: Brake flash/strobe patterns from SMART Turn Signal module will NOT apply flash/strobe pattern to any 3-wire (all red) added lighting product without a separate Brake Y Harness (sold separately) and Magic Strobes™ Brake Light Flasher (sold separately) . Contact our Technical Support Team to discuss installation and proper operation of all lighting.
Custom Dynamics® smoked (included) or clear deuce-style motorcycle turn signal lenses required for proper installation and DOT/SAE compliance; OEM lenses and ProBEAM Bullet Bezels are not compatible.
