A marvel of electronic wizardry, this module makes single filament or single circuit turn signals on the rear of the bike function as running lights, turn signals, and brake lights! It can be used with our L.E.D. or Halogen Silver Bullets, our incandescent Fender Strut Lights, stock turn signals, or any single filament light you may already have installed on the rear of your bike. Completely plug-in for most 96-newer Harley-Davidsons® with single filament turn signals and a taillight with running and brake functions. Compatible with 02-later H-D factory cruise control.
Direct plug-in for: 96-08 Softails; 97-08 Dynas, Dressers, Road Kings; and 99-03 Sportsters. For installation on earlier models or 04-08 Sportsters see 8-Pin Hardwire, or 6-Pin to 8-Pin Adapters listed in the Specialty Lighting section.

Important: P/N 4859 is not compatible with aftermarket or accessory modules that alter the functions of the stock taillight and turn signals. If you have already made modifications to your bikes taillight and/or turn signals, you will have to return your bike to stock form before installing our Controller.

Bikes equipped with factory security system and low-draw L.E.D. lights also require P/N 4857 - Alarm Compatible Load Equalizer.
