Quad Headlight Questions
Hello all,
I've got an '81 GMC Sierra with the quad headlight setup, but saw another similar year truck with all four headlights running the low/high beam setup, I've got the 2 low/hi and 2 hi only... Wondering how I can make that work in my application? I'm also considering upgrading to HID Projectors, so it would be nice to have all four on the low/high style, not just two and two... What's everyone's thoughts?

It's in the harness. There's at least one guy on here who can build custom harnesses, I would give someone like that a shout.

Re: Quad Headlight Questions
Here is the guy hes talking about http://67-72chevytrucks.com/vboard/s...d.php?t=522485 And on the hid projectors make sure you spend the money and buy good ones not the ebay cheapo knock offs.A good set will run you 300 bucks so your looking 600 for all 4 lights anything cheaper i would stay away from.

Re: Quad Headlight Questions
On my '87 all four lights come on when you hit the brights.
I didn't do anything to it, so I assume(d) they were all that way. K
