A Run Turn Brake module or RTB module is an easy addition for greater visibility and allows your motorcycle’s turn signals to operate like the tail lights in some older sports cars. They’ll stay on constantly at 1/2 or 3/4 power (running lights) and go to full brightness when you hit the brakes or use the turn signals. Many chopper guys with the super wide rear tires don’t have space for a traditional dedicated brake light and only have turn signals. Together with the addition of the RTB module the two turn signals work together as the brake lights.
NOTE: By law any rear running lights have to be red. If your turn signals are amber, you’ll need to fix that with red bulbs or red lenses. Mine were already red so I didn’t have to change anything.
Hopefully the additional lighting from the rear will make me a little more visible, especially when loaded down with a tour pack and all the luggage we’ll have during our up coming trip.
