I'm looking to improve the headlights on my '91 GMC, (better/brighter). I know I could upgrade the bulbs to something different, but I have heard of wiring them so that all 4 lights are on when you switch to hi-beam. (good wiring, relays,...) Anyone do this? Is there a kit available? Thanks for any help! -Gerald.
Yes the kit I know of is the Painless. 88-98 think there might be one or two others. If your real good at wireing you could make up one too.
