Kuryakyn Run-Turn-Brake Controller for Metric Cruisers
A marvel of electronic wizardry, this module makes the single filament or single circuit turn signals on the rear of your bike function as running lights, turn signals, & brake lights. The module wires in beneath your seat & is intended for use with L.E.D. or Halogen Silver Bullets or other custom turn signals you have installed on your bike. The unit will work fine with stock turn signals as well, but you will have to use red lenses.
