Headlight Upgrade

[Dylans95Chevy]

do you feel how the bulb goes in....it's not very secure in my mind.....this i will address somehow the next time i break her down...again

Yea, I played around a little bit tonight, Im going to pull the plastic retainers off the old headlights, drill new holes then install them onto the spyders. Should work.

Got the lights installed, still need to properly aim them, but they are worlds better!

I actually re-used the factory brackets on that Suburban I did a little while ago. The lights the guy bought for it were some eBay specials and the brackets they came with were a little flimsy. First time I've re-used the stock brackets, but I've seen a lot of people saying they do it. Certainly makes the install much quicker when it works! Only thing was the lights were aimed way high when I attached them to the brackets, but they adjusted down just fine.

Is there a guide somewhere on how to adjust the headlights on these trucks? How do I get to the screws to adjust side to side?

The adjustment screws are both on top, accessible through small holes. One's a Phillips screw, ones a Torx, I forget the size. The Phillips is up and down, the Torx is side to side. At least that's how it is on my Anzos, other housings might be different.

When I did my headlights I measured and taped a line on the wall level with the bulbs about 25ft away, and then aimed the center of the beams about a foot below that. Taped a vertical line even with each bulb as well and tried to center the beams on that. Did a couple test runs up and down the street and adjusted further. I'm sure there's a more professional way to go about it, but that worked pretty well for me.

I did a lot of work with my headlights when I was doing my projector retrofit on my 2000 Tahoe, and at least on OEM headlamp assemblies, this is not completely accurate.

On OEM assemblies both the up/down and left/right adjusters are torx screws. The metal they are made of is soft and they strip out easily, so I found that a better way to adjust is to use a socket that fits over the adjustment screw. I cannot remember the size, but the adjustment screws are shaped so that you can adjust them with the torx screw or a socket that fits on the outside. I found the socket made it easier to make large adjustments and then used the torx to fine tune the settings.

The left/right adjustment is the screw towards the center plane of the truck, and the up/down adjustment is the screw closer to the fender.

Be careful when making adjustments on OEM assemblies, the metal is soft and the adjusters are brittle, so they are easily damaged. I recommend removing a headlamp just to get a better visual of how the assembly works before putting them back in and making the adjustments.

You are correct, both of the adjustment screws on OEM housings are Torx. Had to go pull one out of the box, been a long time since I messed with the factory housings.

All the aftermarket housings I've laid hands on are as I described, though. One Torx and one Phillips per side.
