Harley-Davidson® CanBus models including 2011-2024 Softail, 2012-2017 Dyna, 2014-2023 Sportster & 2014-2025 Trike models with two rear all-in-one run, brake, turn signals typically carry both turn and brake functions on the same factory wire making it impossible to wire additional amber or red light that functions as turn signal only on the rear of the motorcycle. Our Turn Signal Decoder breaks out the left and right turn signal wires, with easy to connect Posi-Locks®, making it possible to add a rear amber or red light that functions as turn signal only without changing the stock function of the rear lighting. Compatible with additional add-on LED turn signals only.
