This plug and play harness works in conjunction with the SMART Turn Signal Controller and Dual Color Amber/Red 1157 rear turn signals to feed brake signal to any 3-wire (red non-sequential) lighting product so that a separate Magic Strobes™ Brake Light Flasher (sold separately) can be installed to provide brake light flash/strobe pattern to those 3-wire products that are otherwise not affected by the SMART Turn Signal Controller.

This product is only required when SMART Amber/Red LED 1157 Bullet Turn Signals with Controller is installed on the motorcycle in conjunction with any Custom Dynamics® 3-wire (red non-sequential) lighting product and Magic Strobes™ Brake Light Flasher (sold separately).

This is NOT required to flash/strobe any Dual Color or Sequential (4-wire) product.
