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; not just brake/turn like our competitors! It can be used with our L.E.D. or Halogen Silver Bullets®, our incandescent light you may already have installed on the rear of your bike. Completely plug-in for most '96-newer Harley-Davidson's® 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-'07 Softails, '97-'07 Dynas, Dressers, Road Kings; and '99-'03 Sportsters. For installation on earlier models or '04-'07 Sportsters special adapters are required (sold separately).

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 or L.E.D, lights also require P/N 4857 (sold separately).
