What did you do to your NBS GMT800 Tahoe/Yukon Today?

[Sam Harris]

That’s why I made damn sure mine were correct and lined up horizontally before I baked the lenses back on. Didn’t think they would survive another disassembly. Sorry to hear you are having trouble.

I’m not brave enough to do this myself. Who wants to make me some projectors?! [emoji16]

I would if it wasn't such a pain in the ass to swap the bulb holders kn the denali

thanks for reminding me. nevermind, scratch that idea

It can be quite the project that's why I chose the denali headlight over my spyders. The denali is a fairly easy retro. Although I'll be back at it again today I've got to rotate my drivers side projector a little and possibly shim my bulbs.

Did you make any progress or hows your retro going?

I *THINK* we finally have it done. About 16 hours into the project in the last 7 days.

We had to modify the CB&D brackets a lot, to swap the projectors upside down, so that the solenoid would be on the bottom of the bracket.

Added the 4 high mod and my brights finally stay on.

All that's left is to aim and test them once it gets dark.

Yeah I didn't do any baking for this set. Might take them out and bake them to pull out that ugly ass yellow reflector tho.

I'm going to be building another set with the 7.0 kit just cus I want to see if all of the problems I encountered were due to user error, or what the deal is lol.

If my mom doesn't want them on her Denali, they'll be up for sale

Wait-the projectors are upside down? How are you going to get a cutoff line? They’re not designed to be upside down. Am I missing something?

Got the spindles on last night. Turns out my I need all ball joints replaced. I’ll do those and toe rod ends before alignment. Set the toe to get me by for now. Track width is wider up front so I’ll have to get spacers for the rear also. Very happy with it over all

Were the ball joints on their way out, or did they get messed up in the process?

On their way out. Tie rod ends are good but all the boots are tore and dried out on everything

Good thing you saw them now. Def wouldn't want a ball joint giving out while you're driving.

dunno man, dunno.

I did all of 30 minutes of research before impulse purchasing all of this stuff, and diving in.

I'll try to explain. My terminology is probably all messed up and that's what's causing the confusion.



so if you look at this pic, the Solenoid wires are at the top of the light, or bracket, or whatever. because of how the lens reflects light, this meant that the high beams activated downward:




don't mind the date, I haven't taken the time to set it up.

so basically we had to cut the bracket, so that the solenoid would be on the bottom of the housing/light/projector/whatever, as seen here:

Those are definitely upside down, that's not really gonna work plus you'll blind oncoming drivers. There needs to be a clean cutoff at the top so the light doesn't go upward into oncoming traffic. It should be a nice level line with 2 steps up as it goes from left to right like these in my Silverado. That way you can also level the projectors so the lines are all level and then adjust the up and down so the step ups are correct. The left is lower because that's where oncoming traffic is. The right steps up so you can see road signs, etc.

Edit: the solenoid opens up the cutoff bracket so there's no cutoff line and the full light output is unleashed. By having them upside down, it's like having them on high beam constantly only the cutoff brackets are blocking the light from going down in low beam mode and in high beam mode they're lighting up more of the ground. You will definitely blind people plus there's no real way to aim them.
