got mine from am-auto parts on ebay for 174 included bulbs, but havent installed them yet because i been fighting with suvlight.com to get the wiring i paid for 2 months ago. #@$%!
The only thing making my lights better on the 97 was sport headlights. You have to cut some sheet metal to install. I used 2 sets of relays, one controlled the 9004s and the other the 9007s. The whole thing cost about $300 but money well spent. The hardest part was getting the original lite assys out.
Oh Baby look at these http://www.lmctruck.com/icatalog/de/full.asp?page=22 Hmmmm . . .
I think I like the Black with two lamps PN 56-6908 ? ? ?
Those are for 3rd gen 03-05. You need the 6904
The OEM Sport wiring never uses the low beam filament of the inboard (9004) bulb. Low beams use the outboard (9007) low beam filament. High beams use the four high beam filaments.. . .
What's the best solution for a low beam that doesn't blind other drivers, and what's best for high beam?
What does the factory sport light setup use for high and for low?
Just a note... . I've never replaced a bulb on my headlights. I've been running like this for 50k (both filaments, stock lamps), so I'm not too worried about it. So as far as having to replace them because of running both filaments, I don't think it's gonna make a huge life span difference.
