Adjusting the Headlights on SLT(Projectors)


Recommended Posts

If you don't know just adjust it while pointing against your garage door. I count how many revolutions I make on mine so I can keep them level and even.

open hood.. look at the top of the light... down inside the hole is a plastic screw to adjust.. I believe it's a white plastic screw.

that's what I saw but wanted to make sure before cranking. Again, for some reason these lights have me second guessingmyself!!! lol

Back on my old 2002 Silverado I did a HID projector retrofit on a pair of housings. So I did a lot of research and spent a LOT of time making sure my headlights were aimed perfectly after I was done. Using this guide below, I had the projectors aimed perfectly on a lifted and leveled truck. They were bright to people with low cars, but they weren't pointed at the ground where they were useless.

 

Here are my tips for aligning/leveling headlights.

 

1. Park 25 ft away from a flat wall, on a level surface.

2. Measure the height of the beam of light coming out of the projector right next to the bumper of the truck. So stand next to the truck and measure the height of the beam.

3. Measure the height of the beam projected onto the wall.

4. Adjust the projectors so that the beam projected on the wall is approximately 2.5" to 3" lower than the height of the beam at the truck.

 

 

It helps to cover one light and to them separate to get them near the 2.5" to 3" lower than at the truck. Then project both at the same time and get them even while making small tweaks. Either match the lower step of the cutoff or the higher step. Sometimes its easier to match the lower step. Luckily these projectors have a very nicely defined cutoff throughout the beam, so it should be relatively easy to align them both to the same height.

 

Keep in mind, projector headlights have a slopped cutoff. meaning the left side is lower than the right side, and you will see a step right in the middle of the beam. If aligned perfectly the steps of both lights will blend perfectly when shown driving down the road. (However you will be able to see each step clearly on a wall at only 25ft, so don't think you need to make them blend at that close of range.)

 

I actually think these projectors are aimed a bit high from the factory on my current 2014 Sierra. I have had several people flash their brights at me, when I am going down the road with just my low beams on. I also noticed that they aren't shining on the road as much as I would like at night.

 

 

And for anyone interested, here is a link to my build thread of the HID projector retrofit on my old truck. It was a few years ago when I was still in college. http://www.gmfullsize.com/forum/showthread.php?t=160168&highlight=blackknights

Hi Guy's,

I know how to adjust any of the old head lights but these have me a little nervous about for some reason....After adding my 2.5" RC Lift I get the old flash every once in awhile. Does anyone which screw does the elevation on the Projectors? Thanks

 

Sir, do you happen to have the factory torque specifications on the bolts/nuts you tightened when you put your RC lift kit? My kit should be here next Monday and I'm in need of the factory torque specs for the bolts/reinstall

Sounds good! How was the kit install? I've installed sway bars and coilover kits on cars before but never lifted a truck, tiz my first...
