Custom Dynamics® SMART Amber/Red LED 1157 Bullet Turn Signals with Controller (sold separately) includes the SMART Turn Signal Controller which feeds selected brake flash/strobe pattern to the rear Amber/Red LED turn signals, ProBEAM® LED Run/Brake TriBar (sold separately) and any 4-wire Custom Dynamics® lighting product which has Squential and/or Dual Color functions.
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.
