LED Daytime running lights?

[rsnellingsgl]

2018 LT now has this feature.

Well, it’s about time! Can’t believe they excluded any models. You pay $60K for a vehicle and you should expect it to have LED running lights. Chevy vehicles that cost half that much have them!

The LED light stip looks like something from a 2004 Kia. The headlights in my 2017 Tahoe are awful too. My 18 BASE model Accord had LED headlights and nice LED running lights. Headlights are really my only complaint in my Tahoe

I talked to GM arabia to retrofit my tahoe 2016 and my request was rejected !!

Can anyone contact GM us or know how to and ask them to retrofit it to older models i own a 2016 lt2 z81

Ok, so if I'm understanding all of these pages correctly: you can't install LTZ headlights into a non-LTZ 2015-2017 truck and get the bright LED running lights? The only way to get the bright LED running lights in 2015-2017 trucks is to install in-line capacitors and change up the original headlight harness? Or what?

I really wish a someone sold a kit/work-around for this. Somebody could make some money.

This is because LTZ is not available in 2018.

No, the entire line has them. It has nothing to do with the LTZ "not being available" (it's replaced with the premier).

I checked the headlight assembly for 15-17 tahoes suburbans also the wiring harness theres no difference than 18 models .... now we need to ask gm to retrofit it or release an update or something

So, are you able to buy the LTZ lights and just install them then?

The only problem i meant was the retrofit of the bcm mods needed

BCM...Body Control Module, ok. So...here's what's understood:

LTZ headlights:
*Have bright DRLs (Daytime Running Lights - LED light bars)
*Have HID main headlights
*These headlight units are different part numbers (than non-LTZ models) because of the two adders above.
*You can't just swap the headlights and expect the headlights to function like an LTZ due to the BCM (Body Control Module) not programmed to function the DRLs appropriately.

Ok, just went and talked to the guy at the dealership that does all the BCM programming. He said he gets the request a lot. He said there’s 6 wires per headlight unit that would have to be run to the fuse box then to the BCM. He said it would void your warranty and GM won’t let them do the install. He said it’s not impossible, it would just be very difficult and wouldn’t be backed by GM.

Any luck out there ?!

I think after nearly 5 years of failure to find a solution, it's probably safe to say a practical one doesn't exist...

I asked about an OEM fog lamp kit and the dealer said to trade the truck in for a new one. Yeah, right!

Why can’t GM make accessory kits like they did 10 years ago?

 

[NappyBoy]

Any updates ?

any heroes out there ?

I used the kit from GenDIY linked earlier in this thread and it worked perfectly.

The 2003-2014 trucks don't require BCM reprogramming, the 99-02 do but fogs are an option in TIS, and it appears the 2015+ SUV's and 2014+ Trucks require it for the fog lights. There is no option in TIS to turn them on. I'm working on making mine work like factory, but the BCM programming is the current challenge.
