Over all I think the lights look great and easy to install. I'm happy with them and would get them again.This kit is complete with extra wiring jacks. The jacks are there to use when reversing the wires if they don't light up. It must be a common problem, that's what happened to my bike it was no big deal. The drill size they tell you to use for the grommet is wrong that's no problem just use a bigger drill. I used a step drill bit.
