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 is Mike Green. I want to help you save time and money repairing your vehicle. I have 20+ years experience restoring and repairing cars and trucks. My company, 1A Auto, sells high quality replacement parts over the internet. In this video I will be showing you how to install these parts. By the end of this video, you will know how to install them and where to get them, and that is going to save you time and money. Thank you and enjoy the video.
In this video, we are going to replace the parking light on a 2004 Sierra 2500, which is basically the same as any 1999-'06 GMC Sierra. This is a pretty easy process, it doesn't require any tools. There is 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 and then once it is out, you can reach in behind and unplug the lights. They're basically just little teeth that you can pull with your thumb and they unplug. Then the parking light is actually snapped in. There is a little bracket that goes into the side there, and then a little piece that you squeeze and snap out there, and you can see it, switch hands here and I'll push on that tooth and the light will pop out.
Then you just pull it forward and twist out the bulbs, and you can now service either those bulbs or if you need to replace the whole parking light because it got damaged or broken, you can do that. Then to install is the reverse of the procedure, insert the harnesses and twist to lock in. Side marker light and you want to get the inside tooth in there first. Then you can see that at a little better angel here. That just presses right into that slot and locks in. Then you re-install your headlight. At this time, just to show you, you can service the headlight bulbs if you want to, just twist and pull them right out. That's the high beam, same thing with the low beam. They just twist and pull right out. If you were replacing that headlight, you can see that black bracket, you might be able to bolt that on to the new headlight or if you headlight assembly comes with that whole thing, then it just goes in that easily.
Just place the light back into place and use your pins, twist them into place and lock them and there you are. You've just replaced the parking light and we will do a quick test. The running lights, the low beams, high beams, and signals just to make sure and you see actually our side marker light is not working, so we will actually go back in and replace that small bulb and fix that side marker light.
We hope this helped you out and thank you very much. This video was brought to you by www.1AAuto.com, your source for quality replacement parts and the best service on the internet.
