I have a 66 C-30, and want to improve the lighting. I've noticed that LMC, and a few other companies, have a headlamp relay/wire loom kit for adding halogen, or "Euro style" headlamps. Has anyone used one of these, and are they worth the money? Also I want to add cab lights.......looking for a style that would be close to what was available in the 60's. Any suggestions? Thanks!
