Get the Harley run,brake, turn signal module. No wiring problems to worry about. You just unplug your wiring harness for the lights and plug this unit inline. Easy and works great. As for the red, it's just a matter of changing the lens covers. There is a little gap on the bottem between the plastic lens cover and the chrome bullet light housing. Use something thin and pop the lens cover off and snap the new red lens cover in place. I think the module comes with the lenses. The module makes all rear lights on at the same time for running and the signals blink when you turn them on. From a distance at night it makes the rear of your bike look 3 feet wide. Really made me feel more comfortable.
