Will 2016 SLT LED Headlights work on 2016 SLE???

4emeryj44 · February 4, 2017

Okay so I have searched this and can't seem to find an exact answer. I know a lot of people are converting the 2014/2015 headlamps with the 2016 LED's and getting a harness to convert. I had a 2016 SLT with the LED's and they were awesome, long story buy I had a GM Buyback on that trucks, so I bought a SLE that I liked. To convert a 2016 SLE with HID's to the LED headlamps what needs to happen? you would think that the harness would be built into the headlamp and it's just a plug and play but I presume that's incorrect. Anyone have any info on this? My old truck is sitting at the Dealer where I conducted the buyback, and it's being "donated" to a local autoshop or something, and I want to know if I can just plug the LED's in and basically swap headlamps with the dealer. (I am on great terms with this dealer now, and would be willing to BUY the headlamps from the dealer)

I can share my findings with my 2016 Silverado LT. It **should** be the same for Sierras.

I wanted to change the tail lights from the standard incandescent to the LEDs that come with the LTZ and higher trims. The harness that connects to the LED taillight are obviously different since the taillight side uses one incandescent socket for the reverse and a (4) pin connector for the lamp. The harness set was different. Where they connected underneath the truck was the same.

Gonna take a stab and say the harness for the headlights might be different. Also keep in mind that while I was able to "Plug and Play" my tail light and harness, I still got hyperflash since the BCM is programmed for Non LED. I had to add resistors to fix that.

Thank you for the response, good info. I would ultimately like to get the tail lights converted as well, but I'm more concerned at this moment with the headlights.

Interested in this swap also. I'm curious if a 2015 standard headlights (SLE) to 2016 LED swap can be done by using only a harness, or is there more to it without "starting" with LED headlights.(I know many have done the LED old style to LED 2016' style) I have a 2015 GMC 1500 Sierra SLE with non-LED headlights. (Obviously I would purchase some Denali 16' LED headlights)

Mmmm?
