No Tools Needed
1. Removing the Pins
Open your hood, and locate the pins that hold the headlight in. Twist these pins, and remove to release the headlight from the mounting bracket.
2. Disconnecting the Headlight
Pull the headlight forward, and locate the low beam and high beam connectors. Disconnect them by putting your thumb into securing clasp and pulling.
The headlight is now free from the vehicle.
3. Connecting the New Headlight:
Bring your new headlight over and reconnect the low beam connector. Do the same for the high beam connectors.
4. Replacing the new Headlight
Slide the headlight back into the vehicle, making sure the low beam connector is pushed back into the hole so it doesn't get caught between the headlight and the mounting bracket.
Press everything down and lock them back into place with the pins.
5. Test the New Headlight
Make sure to test both low and high beams.
This video will detail headlight replacement on 2000 to 2006 GM SUVs pickups.
This replacement is similar for our 2000 to 2006 Yukons and Yukon Excels, 2000 to 2006 Tahoes and Suburbans, 1999 1500-series pickups to Sierra and Silverado, and 2007 classic series.
The headlight procedure is the same for all trucks that look similar to our example truck a 2002 Yukon Denali. It has the projector beam headlights. The procedure to replace the headlights is the same, whether or not you have the projector beam headlights or regular headlights. No tools are required for this and it only takes about three to five minutes.
The process to remove the headlight is very easy. Open your hood, locate the pins that hold them in, twist them, hold them up, and remove them to release the headlight from the mounting bracket.
Then, pull the headlight forward. Locate the low beam and the high beam connectors. Disconnect the connectors by putting your thumb into the connector and pulling.
Now the headlight is free from the vehicle. Get your new headlights and reconnect the low beam connector. Now reconnect the high beam connector, and then slide it back in the vehicle, making sure that on the pigtail of that low beam connector is pushed back into the hole so it doesn't get caught between the headlight and the mounting bracket.
Now press everything down and lock them back into place and you're done. Do a test and you're set.
Again, this goes for most 2000 to 2006 GM Trucks and SUVs.

Hi, I'm Don from 1A Auto. I hope this how-to video helps you out, and the next time you need a part for your vehicle, think of 1AAuto.com. Thanks.
In this video, we're going to show you how to service the bulbs, as well as replace the entire headlight assembly on this 2002 Chevy Suburban. It's the same part and similar process on these Suburbans from 2000 to 20006. There are no tools required for this procedure.
Just pull out on these rods and then lift them up and out, and now your headlight will pull free. You do have to maneuver it by pulling out on your grill a little bit. Just lift up on these tabs and pull these harnesses free. Now to service the bulb: you just twist the socket counterclockwise and pull it out. Then twist your new one in clockwise to lock it. Both bulbs are the same procedure.
On the left is the old headlight assembly; on the right is the new one from 1A Auto. You can see they're identical, and they're going to fit exactly the same. We also have a couple performance options at 1AAuto.com that will also fit just as well.
Take your new headlight and reconnect those two harnesses. Then push the outside end in first, pull back on your grill, and push in the inside end. Once you have it back in place, you want to just slide that rod back down in. Once the headlights lined up properly, it'll slide right down, and just push it in to lock it. Do the same thing with this one and then you're all set.
We hope this video helps you out. Brought to you by www.1AAuto.com, your source for quality replacement parts and the best service on the Internet. Please feel free to call us toll-free, 888-844-3393. We're the company that's here for you on the Internet and in person.

This replacement did not fit as well as the original equipment. The locking pins did not insert as smoothly. And once installed the light is on a canted upward position.

I purchased left and right lites for my 2000 Chevy Silverado stepside. These lites as as close to GM that I have found. Torx socket adjusters, lens attached to body of lite housing same as GM, lite housing is strong as GM. Would strongly recommend these lites. PS : I purchased another set of lites first from a local accessory shop and they were total junk, they would not let me return them no problem , threw them in trash and then purchase the above from 1AAUTO WHO STAND BEHIND THEIR PRODUCTS.
