R-T-B was a piece of cake to install. A load equalizer was included with the controller and was needed to get the turn signals to function correctly.
Since all of the lenses in the rear of the bike were clear colored, I wanted to replace the amber turn signal bulbs with red turn signal bulbs (Kuryakyn P/N 4620). These particular bulbs were on a significant back order so I ended up getting red turn signal bulbs (Kuryakyn P/N 4814) and filing off one of the pins. That did the trick and I am very pleased with how it turned out!!!
