A quick video tutorial on how to remove and replace the tail light / brake light assembly on a 2015 – 2020 GMC Yukon and Yukon XL.
The GMC Yukon owner’s manual contains the following information on the removal and replacement of the tail light / brake light and reverse light:
The taillamp on this vehicle is an LED. For replacement, contact your dealer.
To replace one of these bulbs:
1. Open the liftgate.
2. Remove the taillamp closeout cover from the lamp assembly by pulling rearward from the top and bottom at the same time to unfasten the snap tabs.
3. Remove the two screws from the taillamp assembly.
4. Pull the taillamp assembly straight back to remove.
5. Turn the bulb socket counterclockwise to remove it from the tail light assembly.
6. Pull the bulb straight out from the socket.
7. Press a new bulb into the socket, insert it into the tail light assembly, and turn the bulb socket clockwise until it clicks.
8. Reinstall the tail light / brake light assembly and tighten the screws.
9. Reinstall the tail light / brake light cover by snapping it into place.

Great video. Very helpful and super easy to change out !!! Thank you
Is the same fix for a Yukon XL rear passenger light?
i feel really accomplished that i was able to do this part change by myself, thanks for the video!
Thank you so much! You got right to the point!
This is great! I have been trying to understand how GM put the thing together. You have made it simple for me. Thanks.
If just the brake light doesn’t work and everything else does, do I replace everything?
Thanks dude! Got my wife’s Yukon inspection ready in less than 10 minutes.
THANK YOU SIR GREAT VIDEO
Just saved me about 100 and hrs of leaving my Yuk at the dealership…thank yoh!
Where is the best place to get a rear right assembly? I've seen some on ebay for $235…
Which color wire is turn signal wire on right side ?
Thank you!!! Definitely helped me today!!! Gm told me they would fix 1 for me for $1500. They do have a recall but it’s only up to like 70,000 miles. So after that you’re on ur own. I ordered lights off online for $300 and they have a 10 year replacement warranty. Saved myself so much money
I did this myself. Some part always breaks inside..Solder back that piece that’s inside and good as new.. been working great for 2 yrs now.. and it only cost me 15 on Amazon for the soldering kit
Thank you for the video. In the comments, one person mentioned that gm has a silent recall on the tail light. I'll investigate that opportunity. If it falls through, I'll visit a junk yard before spending $800.00 from the dealer
Perfect! Mine just got hit by someone in a parking lot.. having to replace the whole unit for a small crack.
Great video! Concise and to the point!
Both of my brake lights are out. Dealer said $2000 dollars to replace them. Where can I purchase two for a good price? Where did you purchase from? Thanks for this video by the way.
