Push down the two tabs to anchor the head light assembly.

I want to help you save time and money repairing and maintaining your vehicle. I'm going to use my 20-plus years experience restoring and repairing cars and trucks like this to show the correct way to install parts from 1AAuto.com. The right parts installed correctly. That's going to save you time and money. Thank you, and enjoy the video.
In this video we're going to show you how to remove and replace the lights or the headlights on this S10 Blazer. This is a 2000. It is similar for some of the S15 Jimmies as well. You don't need any tools unless you're looking to adjust them. Then you'll need either a Phillips screwdriver or a small socket and ratchet.
Removing the headlights is pretty easy. There's actually two tabs right here, which you pull up and off. Be careful not to drop them. Once those tabs are removed, the headlight comes forward. Okay, if you're just looking to replace your headlight bulbs, you could just grab them and twist. They come out. Disconnect them here by pulling back on these tabs. Disconnect the harness. This side marker just twists and pulls out. This one here twists and comes out. Tab goes out and now your whole assembly is out. If you did break your headlight for some reason or whatever, new headlight from 1A Auto, you can see it's all the same, nice chrome surround. Back is going to be all the same.
As far as aiming the headlight, you've got two screws here. They have both a Phillips and it looks like about a seven-millimeter socket head. This one you can reach from the front. This one here, you reach by using an extension and going right down through here I believe. Yeah, so you would go right through there. What you can do at first is to just adjust it so that the distance between here on your old one and then the distance between here on your old one matches the new one. That gives you a good preliminary aim.
About installation, obviously connect the harnesses. I did swap over the bulbs already. Plug in the harnesses. Okay, plug in your marker light. You go to put the light in, you can right there, and there are two big slots. On the light there are these two tabs. Those two tabs go into those slots. Once you have your lights hooked up, you just want to make sure that your harness here is not interfering with these tabs going into those slots. I'm going to put the light in. Make sure it doesn't get caught on this cable, your hood latch cable. Put it into place. Kind of push the bottom in first. You are going to feel those tabs go into the slots. Then look back in the back. Make sure you're lined up. Push it down and back.
Then the back, it's going to come through these two square holes here. You can see there's the light. I'll push it through. As you're putting these on, you want to put the large area around that and then that goes down. The slot goes down and over that. Push the light back. Push your plastic retainers down. Then again, like I said, you'll now adjust it by turning this screw. I believe counter-clockwise brings the light down and clockwise brings the light up. Then down in here, I believe, clockwise probably aims the light more to the left. Counter-clockwise probably aims it more to the right.
In order to get your beam correct, you want to measure the distance from the floor up to your light, and then from 20 feet away you want to make sure that the beam is pointing straight. A low beam should be pointing one inch down, and a high beam should be pointing straight ahead as well and it should be pointing level. If you park this 20 feet away from a wall on a level surface and you measure up and it is say, 32 inches on the wall, the concentration of beam should be a 32 inches, and the concentration of beam for the low beam should be at 31 inches.

In this video, we'll be replacing the headlight in this 2001 Chevy S10 Pickup. Basically the same as any '98 to 2004 S10 pickup with the Style lights, very easy procedure, you don't even need any tools and we'll get right to it.
You're going to open up the hood and then there's two locking tabs that you see on the top of the screen there, I'm pulling up on them. Place those locking tabs there where they're safe and they don't fall in and you don't have to fish them out, like I did a couple of times. Then, you pull the headlight forward and it's out. Then, you can unplug your lights and service the bulbs, if you need to do that or if a rock jumped up and hit the light or whatever, you can replace your entire headlight, too.
Then, there's two slots that I'm going to spray some lubricant on just to make it easy to get everything together. Right there, that slot and that slot. Then, I'll show you the tabs. These tabs go into those slots, okay? The other thing is you don't want to pinch your wires. I'm going plug in the harnesses here and I'm going to show you how to make sure you don't pinch the wires. Those tabs I showed you a few seconds ago, they also have tabs that come forward. Once you have one of these lights in your hands, you'll understand what I mean. What you do is you take the harnesses and you put them up on top of the protruding tabs. That keeps them from getting in behind the other tabs and getting caught between the metal and the plastic of the headlight, okay?
Put your headlight back in there. This is a little ballet of pushing on the backside of the headlight, pushing in and down at the same time and then getting everything to line up. You can see down, there's a couple of holes that you can see down into to see how things are lined up. Once you get it, it goes in and then you put your locking tabs, which I didn't do a very good job videoing there, I apologize. You put your locking tabs back on and you're all set.

Units needed to have my old mounting brackets transferred to the new units, The ne units mounting brackets were loos e and rattled upon installation cause the headlights to look like they were bouncing and loose while going down the road. Once we transferred the old brackets they were stable and tight. Plus the light bulb sockets were somewhat butchered and hard to place the bulbs in while upgrading the bulbs. After all the extra work we had to do to get these working satisfactory....they do look nice hence the 2 stars. Other than that it would have been 1 star for the installation modifications we had to perform.
