How to Replace Lower Headlights 2003-06 Chevy Avalanche 1500
Created on:
Tools used
Flat Blade Screwdriver
1. Removing the Headlight
Push the lock tab and slide the headlight out
Twist the bulb socket counterclockwise out of the light
Remove the headlight
2. Removing the Lower Headlight
Pry out the L-pins
Pull the L-pin straight up
Pull the housing out a bit
Disconnect the wiring harness
3. Installing the High Beam Housing
Feed the housing into the body
Connect the wiring harnesses
Press in and lock the L-pins
Turn the screw to adjust the lights
4. Installing the Headlight
Turn the bulb sockets clockwise into the light
Line up the headlight with the clip slot
Click the headlight in
To open the hood on this 2005 Avalanche, open your door. Pull the release. The secondary release is actually under the emblem here. Push it to this side, and lift the hood up. To change this headlamp, you first have to remove the turn signal lamp. Reach down, push this tab in. Push this tab in right here, pull it out. Now, we're going to pull the headlamp away from the grill, off the tabs that it's mounted on. Push this in. Turn it counterclockwise to remove the bulb and socket. Turn the marker light bulb counterclockwise to remove it.
There are two pins, L-shaped pins, one here and one here. I'm going to unlock those to remove the light. I'm going to use a flat-bladed screwdriver to pop it out. Pull it straight out. Same thing over here. Pull it straight up and out. Put those aside. Headlamp is free. I'm going to unlock the connector on the lamp on the bulb and push it down. Pull it off. I'm going to undo the other side. I'm going to pull the clip or the lock on it away from the headlamp, and I'm going to push down on the connector at the same time to pull it off. Then, you can lift the light up and slide it out.
Here's our old yellow and discolored headlamp. It's all pitted from going down the road. You can't really see that well out of this. This is our new one from 1aauto.com, perfectly clear. You're going to have great night vision with this. It comes with two new bulbs, and look at the old one. It has the same style of mounting and the same shape. It'll fit great and look great.
I'm going to take our new head lamp. I'm going to feed that up like that. That has the adjustment for it. I'm going to plug in our connectors. Place it into the little mounting area. We'll reinstall these L-pins. This one will slide down just like that, and I can move it around a little bit to line it up. You flip it over and lock it in. Same thing with the other side. You need to wiggle the headlamp a little bit to get it in there. You want to flip it over and lock it. The headlamp is installed.
Now, reinstall your turn signal lamp. Turn this clockwise to lock it. Install the side marker bulb. Turn it clockwise to lock it. Put these tabs into the radiator support. Push this up and in. If you need to adjust the aim of the headlamp, you can turn this screw in or out.
This is a basic tutorial on how to aim the headlights on your vehicle. Find the axis of your headlights. This is usually indicated with a small dot or the headlight bulb size on the lens. If not, it's the actual center point of your headlight bulb. Transfer this mark to a vertical wall with a preferably dark color that'll allow you to back up 25 feet. Pull up and find the center line of your vehicle, as well as the center line of your headlight axis.
Mark the wall with the height of the headlights and a straight line going across at that axis height. Back your vehicle up 25 feet from the wall to the front edge of your vehicle's headlights. Turn your headlights on, and locate the adjusting screw, usually on the back side of your headlights. You'll want to rotate this until the passenger hot spot or focus of the beam is approximately two inches below the line and the driver's side is four inches below the line. We change the heights on each side so you can still get a good beam to the off side of the road on the passenger's side and have the driver's side low enough to not blind oncoming traffic.

Found these replacement lights for the Chevy Avalanche at 1A Auto and they were by far the least expensive of where I shopped on the Internet. Came very fast and in in excellent condition. Installed them in minutes, it was plug & play, the easiest installation possible. Love my new headlights and parking lamps. Oh yes their customer service helped me at first, answered my questions and found me the order numbers on their website, very helpful, very polite. I will call them again for future business. Thank you 1A!!!!!

Items arrived quick and in tack. Then, believe it or not, even as a 57-year-old woman, I watched one of your videos and installed them myself probably saving around $75 in labor costs. They fit perfectly in my Chevy Avalanche. Thanks, 1A!

I messed up the front end of my 2005 Chevrolet Avalanche w/ cladding and needed to replace everything. This headlight assembly set was the best value, with the best quality, from a great company. The lights look fantastic, they included the halogen bulb, but not the incandescent. Easy installation. Couldn't be happier.

Been dealing with fogged over lights on my Avalanche for longer then I care to admit! Also had one of my running light zip-tied in! Finally broke down and ordered a full set, the price really sold me!
One minor glitch, 1A Auto only sent one of the headlights! Couple of minutes on the phone, problem fixed.
Watched the video, very simple replacement. Took me about 30 minutes, most of which I spent cleaning before I put things back together.
All in All, very satisfied!
Great OEM replacement

I have ordered from 1A Auto in the past and will continue to order from them again. Purchased a complete set of replacement headlights and fog lights. I had been using the restore kits for a few years now and was just tired. I know that eventually, these will need restoring since it is only plastic, but that will be years from now. Great look and OEM fit. Bulbs sent with these are a bonus but not part of the order. As always, fast shipping and excellent customer service.
Excellent

Perfect fit, quality product.
Installation and associated video could be updated. It took considerably longer to install then I anticipated.
After installing and removing several times I finally caught on how to make it work. This was specific for the driving/fog lamps.
GREAT customer service

I ordered the wrong parts for my truck. Called 1A AUTO to return it. I expected a hassle....NOPE!!! They worked with me for an easy return. Now, I have the right parts that fit my truck. I will ALWAYS be a 1A AUTO customer. THANK YOU. Raymond, Bronx, NY.
Great lights!

Very easy install an 04 Avalanche. Truck looks great and lights are like new again. I took the advice of other posts and added silicone to most of the seams, leaving the bottom open to drain any water that may deep in. It did have a little moisture the next day, but burned off later. Very happy with purchase!
