Quad headlights in '94-98 GMC grille?
Anybody running the older style (glass) quad headlights in a '94-98 GMC grille? If so, could you please post a picture? Thanks!

Re: Quad headlights in '94-98 GMC grille?
While changing to 4 headlights, get the glass/ replaceable 60/55 watt halogen upgrade headlights from LMC Truck. Then also harness for all 4 to light up.
( There is a thread about successfully changing to 4 lights, somewhere in this forum.)

Re: Quad headlights in '94-98 GMC grille?
I had read that you just need the pigtails from the older lights. If there's anything additional, hopefully someone will chime in.
I would like to see some pics of how they look in the later '94-98 GMC grille though.

Re: Quad headlights in '94-98 GMC grille?
This is a thing I wanted to do to my '92 since t was new. I never did it, but I am sure all you need to do is swap all parts involved from harness to mounting. Aside from the lights, the grilles and core supports are the same. So just the headlamp parts are involved. Looks so much better and it's less plastic as well as retro classy. Not to mention the yellow with age you get from plastic.

Re: Quad headlights in '94-98 GMC grille?
I keep seeing the quad headlight swap is a direct swap but it seems there needs to be something that retains each lamp to the core support.
Old school set-ups have a retaining bracket for each lamp (my 89 Squarebody dually does). Did something change w/the OBS platform?

Re: Quad headlights in '94-98 GMC grille?
They are a direct swap as long as you get the compleat assembly from the donor truck, that will include the mounting bracket, headlight buckets, the adjusters and the retaining rings. The picture is from the LMC catalog for reference.

Re: Quad headlights in '94-98 GMC grille?
If you are contemplating this change out consider going to the 4 beam high beam configuration at the same time. I mean you have it all apart anyways, so it would be a good time to kill two birds with one throw.

Good call on the pigtails. I knew they had to be changed, as the lighting styles are different, but getting new stuff makes good sense. Thanks for the info about the other stuff needed for the swap.

Re: Quad headlights in '94-98 GMC grille?
I hate redirecting you to another forum, but those interested in the H4701/H4703 bulbs on a daily driver need to understand that the light output is poor in stock form and the upgrade options are slim. Dropping HIDs/LEDs into ebay lenses creates a hazard for oncoming drivers due to the excess glare.
Here is a great thread on '88-'89 headlight assemblies: http://www.gmt400.com/threads/tech-8...eadlights.946/ The author is a good friend of mine and both of us have continued to research the options. I had a set of LMC lenses in my '96, highs and lows; now I've got Bosch low beams and LMC highs.

Re: Quad headlights in '94-98 GMC grille?
I've thought about this but still on the fence. I would like to do the headlight relay upgrade, but I rarely use my high beams. 4-hi would be cool, but not sure it's worth it in my situation.

I currently have the same high beams as pictured, but my low beams are the Bosch E-Code as shown in the thread on the other forum.

Re: Quad headlights in '94-98 GMC grille?
Just look at these two trucks here. So much better looking, IMO. And it's not just my tendency toward going retro. I like the look of the isolated bulbs with the dark areas surrounding. Looks badder asser to me. I drive a '95 Cheyenne single glass headlamps, so no swappin' here. If I get a fancy one I'll do the change.

I got the LMC kit..... it took me less than an easy hour to hook up the 4-headlight setup.

Re: Quad headlights in '94-98 GMC grille?
LIve changed every OBS I've ever owned to the 4 glass bulbs, and the Hi-4 mod also. All it takes is the headlite buckets, pigtails, correct grille assembly, of course the bulbs, kit for the Hi-4 if you choose to go that way (or the relay and some wire for a homebrew "kit"), not much more. You can also upgrade the wiring to the headlites to provide full power to the lites, sorry l dont remember much more than that and being wheelchair bound nowadays l can't get out there to refresh my memory, but Tx Firefighter (iirc) has a good writeup on it in his last build thread, can't remember details but it's a white truck w/red aftermarket interior. Sorry this is vague and all, trying to help as l can. Bottom line is it's totally doable, looks great, and works as well as you're willing to take it. I even ran some of them through a lighted toggle switch in the lower left corner of the dash to give me both options, overkill l know but when l get started....lol! If you try that be careful, mine threw out way too much light and l had to wrap the toggle in black tape and cut out a tiny diamond otherwise the light was a *serious* distraction lol. Live and learn I recon.

Nope. Those are smaller in size.

I finally realized there was nothing out there. My 4-headlight lens was used on my '88 GMC & '88 Chevy. And the only different 'vehicle' is the GM vans. That's it. Camaro, etc., uses a smaller size lens. ( At a glance, they seem the same size, but they are not) Then, out of the blue, a few years later, Sylvania came up with the "ExtraVision". #'s H4701 & H4703. Better than the regular, but LMC has a better version, you can change the bulbs, and the LMC is also glass. I also know some people use both High Beam lenses & adjust the "low beam downward". ( I can not imagine any car would use a minimum-brightness bulb in '98 - '02 ) IMO
