I thought with all the previous discussion about headlights and such I would share my relay solution.
Recently I rewired the headlight circuit and needed good relays so I went to the local PickNPull and pulled a bunch of Bosch relays from a Saab. Alot of cars use Bosch relays but the Saab has a bunch of them under the hood in the fuse/relay panel so you don't have to crawl under dash boards as in some of the other makes.
These were $2 each and I used some aluminum 1x I had on hand and used JB weld to secure them to the aluminum. I made up singles and a double for the headlights.
