How to Replace Headlights 1999-2004 GMC Sierra 2500
Created on:
Tools used
No Tools Needed
1. Handling the Bulbs
Note: DO NOT TOUCH the bulbs- the oil from your fingers will burn into the light and foul your bulb.
Clean with rubbing alcohol and a soft cloth if the bulbs do get touched.
2. Remove the old headlight assembly
Pop the hood and secure it.
Remove the two anchor pins securing the head light assembly by twisting and pulling them up.
Remove the head light assembly.
Unplug the bulbs and harness.
3. Install the new headlight assembly
Plug in your bulbs, replacing them with new ones if necessary.
Reconnect the harness by clipping it in.
Line up the head light assembly and clip it into place.
Put the two pins back into place to secure the head light assembly.
Close the hood and enjoy your new 1A Auto headlights.
This video is brought to you by 1AAuto.com, your source for quality replacement parts and the best service on the Internet. Hi, my name's Mike Green. I want to help you save time and money repairing your vehicle. I have 20-plus years experience restoring and repairing cars and trucks. My company, 1A Auto, sells high quality replacement parts over the Internet. In this video, I'll be showing you how to install these parts. By the end of this video, you'll know how to install them and where to get them. That's going to save you time and money. Thank you and enjoy the video.
This video, we'll be replacing the headlight on a 2004 GMC Sierra, basically the same as a '99 to '06 Sierra. It is a pretty easy process. It requires no tools. So, with that, we'll get you to it.
There are two pins that hold the headlight in right there and there, and you'll twist those out and pull them up. Then, the headlight basically comes right out. Then, once it's out, you can reach in behind and unplug the lights. They're basically just little teeth that you can kind of pull with your thumb, and they unplug.
Okay, now we're going to replace the headlight. At this time, you can obviously service the bulbs if that's all you're looking to do. So, they just twist in ... or twist out and twist back in. Then, our headlights come with that whole bracket and everything, so if you're replacing your headlights at this point, you're plugging them in and then everything should install just the same way. Plug them in, put the headlight back in there. Take your pins, put them down through. Obviously you have to make sure that the headlight is all the way back in and lock them into place, and your head light's all set.
Now, we'll do a quick test. Just make sure everything's working. The headlight, the high beam, and the signal are not working. Actually that side marker's not working, so we'll really quickly replace that, and then, you're all set. Hope this helps you out. Headlights are pretty easy to service on these GMC trucks.

Ive ordered quite a few times from here and again, absolutely love this site! Its very easy to find your way around. Never had a problem with any of the parts fitting, so I cant give an honest opinion of the exchange policy, but judging by the rest of my experiences I dont believe it would be a problem!! The parts are of good quality and the how to videos are helpful as well. I have also ordered parts over the phone as well, and can say with certainty the operators are very helpful and knowledgeable. Over all I would highly recommend 1aauto.com

Great quality for the money. The clear coat on the outside will give after a few years so I would clear mask them as soon as you get them if you want them looking brand new for many years.

Exactly what I was looking for, great light output especially with the VLED bulbs I put in, OEM quality these are superior to those you buy from recon an those other aftermarket stores, the projector has the perfect cut off an they are both inline
Worth the money

These headlights will use the same bulbs as your originals, which should be a 9006 for the low beam and 9005 for high.

Do these use 9005 low beams, like in the 2001-2006 GMC Yukon/Sierra Denali, it appears they have the adapter for 9005 bulb to plug into the factory 9006 headlight harness?June 10, 2022

New light bulbs are not included with this assembly. Occasionally, manufacturers leave test bulbs in the lights. If you receive test bulbs, you'll want to replace them with your original bulbs or with new bulbs.

I do not see why they would not fit. My vehicle was a 2005 Yukon and I did not have any problems at all.

These will be correct for 2002 GMC Sierra 1500 SLE models and as long as your original bulbs were halogen they will correct for these assemblies.
