I'm always a fan of well-made wiring harnesses. These don't force you to cut any stock wire, so no length is lost, and the stock lights can easily get reattached for reselling if that's an issue. Also, these cut minutes off of installation.

the right side one went bad after just a year. I will need to most likely order another one, but the left side is looking all good!
