2016 SLT lights in 14/15 SLT/All Terrain almost done

Yeah like I thought. You need resistors in the rear.

If you have resistors for the front led, it shouldn't be the problem for the rear signals. It's the low consumption of driving/braking LED tail lights that may trigger the light out on the dash.

That was my belief and assumption, but thought he may test it.

Cool, thanks!

Wow much more advance than other vehicles. I guess I'll wait for your your harness too.

Headlights in tomorrow and can't wait for tails

Now if only someone could figure out how to get that dash in a 2014 SLT LOL

You can.

You are looking at a 2015 Denali Cluster in my 2015 SLT.

There is a thread all about it. If you want the details PM me so we don't run off track in this thread.

Got me looking on cost for a Denali Cluster now... I don't need another mod ?

Sorry guys. It was pretty here all weekend so we went fishing. I have not tested but I see arth did (big thanks for that) and resistors are needed. I will get the harnesses made up this week and start getting them out to you guys!!

KyleGT · February 21, 2017

Installed my LED headlamps with zmnypit's harnesses tonight after work.

For anyone about to install theirs, it's pretty straightforward. Here's a quick "how-to guide" since I didn't see one posted yet.

You need to remove the bumper top pad, then the grille, and then you have full access to the headlamps. There's a 7mm screw on each side from the wheel well through the fender trim/flare and bumper top pad. Pull out on the flare to get it out of the way so you can remove the top pad. There's a T15 torx screw a little further back on the flare you can remove to allow more movement of the flare as well. There is then a 7mm screw going straight up through the bumper top pad into the fender. Once you have those out, you should be able to pull out on the top pad to release it from the retainer holding it up to the fender. Once you get that released, the top pad is clipped into the bottom of the grille. You should be able to pull it forward and the clips should release, or you may need to gently pop it loose with a small flat head screwdriver at each attachment point. There is 4 10mm bolts along the bottom of the grille, and 4 along the top. You'll need to remove the upper cover off the top of the grille first. After that, it's just 4 10mm bolts that hold each headlamp in place. I attached the resistors on the new harnesses to the side of the radiator support with small screws.

I wish I would have taken some pictures along the way, but hopefully this made sense.

Before:

During swap - one old one new

Picture doesn't show the difference between the old and new very well, new is bright white and old seems very yellow

Done!

Definitely need to get LED fogs. Stock ones look very out of place (again, photo doesn't show that very well)

Signals/flashers on:

I did before and after pictures of the light on my garage doors, but the difference doesn't show up very well. I can tell you however, that these headlights are bright as hell!

I also got quick video of the flashers on. I'll have to upload that to YouTube or something and post a link to that if anyone wanted to see that.

Here is mine. Done 20 mins ago. Straight forward! Stunning!

Nice job guys and many thanks to Vann for opening the so-called flood gates for making the conversion super easy.

Awesome to finally see the chrome version installed! Can't wait to get mine installed once the harness gets here

Looks absolutely amazing

No regret what so ever! In person, think I like them more than black housing when lights are on!

Raised to 1250 OBO now. 3 sets. I'm sure he will take 900 again

They look to be out of box brand new. Mounting taps have no sign of ever been mounted. Back of the housing is just too clean to come off a used Sierra.

heatsink

After a little more research, this is actually the LED controller GM has it labeled as the K166L and K166R LED controller if you remove it you will see a 20 pin connector. The case functions as a heat sink as well but the brains are inside of there.
