I did my lights a year ago and for some dumb reason it didn't work. I was frustrated and took the relays and wires back out.
A month later after watching the video a few more times I felt ready to tackle it once again!
This time it turned out fine. It even looks professionally done and that is amazing to me. Wow, what a major difference it made.
I try to NOT drive at night at all. Way too many construction areas and those damn orange cones and concrete barricades confuse me at night, during the day they are bad enough!
