It needs to have a detailed drawing in the package. For the longest time I didn't understand I needed to run a separate power wire for white light section. I use a dedicated fused wire from the battery. I didn't use any of the press wire connectors. If your going that far I soldered and heat shrink tubed the connections. I also added a cheap push button to isolate the battery and lights. I think they look and work great. No issues about the bulbs or sockets supplied. Was worth it for the money and simple to do.
