Brought to you by 1AAuto.com- Your source for quality replacement parts and the best service on the internet. Hi I'm Mike from 1A Auto. I hope this how to video helps you out and next time you need parts for your vehicle think of 1AAuto.com. Thanks.
In this video we're going to show you how to service the headlights on this '99 Toyota Forerunner. It's the same as any '99 to '02 and we'll show you both just replacing the headlight bulbs as well as if you want to replace an entire assembly or both assemblies if yours are clouded, if they've faded, chipped, or broken. To replace headlight bulbs you actually don't need any tools. If you are replacing your entire assemblies you'll need a small flat blade screwdriver, a Phillips screwdriver, and a 10 millimeter socket with a ratchet and extension.
If you're looking to replace a bulb you go right in here behind this headlight and then there's a connector and you have to pull on it and it comes off. Then there's a dust boot here, pull that dust boot off. There's a wire retainer you push in and then pull up and it might take a little bit of force, but it should pop right off. Just bring it out and then your bulb comes out. You can put a new one in just by reversing the procedure. Put the bulb in, wire retainer down and locked into place. Put your dust boot back on and reconnect.
Okay, I showed you replacing the bulb on the passenger side, driver side is the same procedure. Now I'm going to show you how to replace a whole assembly. This will be useful obviously if you need to replace your assembly due to it got broken or if they faded and clouded so you're having trouble seeing at night. New set of headlights from 1AAuto.com will help that problem. The grill is held on by a series of clips. There's one here, one here, two more on the top and then there's a few down at the bottom. What you want to do is go in from the side and the little tab that you press down. You can see I go right here with a small flat blade screwdriver. There's the tab that you want to push down. You'll do this seven times.
Push down on that tab and you pull out on the grill to release it. Push down on the little tab and the grill pulls out. Same thing here located another tab, push down and it comes out. Okay, we go to the top now. Do the same thing with the other side. Go in from the side, push down, pull out. This middle one you come right in from the top. This is the easiest one to see if you want to know how they work. Middle one just push down right there. Phillips screwdriver at the top here. There's a little clip at the bottom, pull it right out. Disconnect that. Grab your 10 mm socket. Bolt right here. Now there are four fasteners that hold the light on and a bolt there. A bolt in underneath there and then two nuts right there.
Again I'll use a 10 millimeter socket with a ratchet and an extension and remove those four fasteners. I removed the two bolts from the inside of the headlight first and then the two nuts from the outside. Pull the light right out and unplug your lead here and pull the lights out. New light from 1A Auto. Exact same as the new light, nice and clear. Just going to plug in exactly the same. Get it onto the two studs over here on this side. Put it in place. Start this bolt over here carefully.
The tip is for these two bolts, put the bolts into the socket on the extension first that way you can reach under there, in there and start them up. That's for the bolts, the first two. Using my extension and just watch it lead in. we'll speed it up, start the bolts in, start your two nuts on and then tighten them up. You want to tighten them nice and firm. You don't need to over tighten them.
Take this small coarse thread bolt, put that trim back on, and tighten that up. You're parking light from 1A Auto it's going to be exact same as your original. If you have one broken or you just want to replace it and make it look nicer. Just make sure that on the side everything lines up properly. Back into place and you're Phillips screw. Okay, before you install the grill take your clips just squeeze them, twist and put them into the new headlight.
Install the replacement grill you basically just put it into place and watch these clips, make sure they all go in correctly and then slide the clips to the side a little bit. To adjust your lights there's an adjuster here that you use a 10 millimeter wrench or socket ratchet on. There's an adjuster down here, okay, with a 10 millimeter wrench or a socket and ratchet. One of them adjust the light up and down and one adjust left to right. Basically on these lights you want the low beam pointing straight ahead and down one inch. You want the concentration of the beam to be down one inch from where the bulb is at 20 feet way. The high beam you want the concentration of the headlight beam to be at the same level as the bulb 20 feet away on a level surface. Obviously you want them pointing straight ahead.

All you need is a Phillips screwdriver, and I'll show both replacing the entire light, as well as just replacing the bulb.
One Phillips screw is right on top here. There's a little clip at the bottom. Pull that right out. You need to disconnect that. This socket twists and this light will pull right out.

Installed easily, especially with the detailed install video on 1A Auto. While installing these I also replaced my front grille insert as well. Great parts, solid prices, and great support. I did change out the bulbs that came with the headlights, for a little bit brighter units. Everything seems to be working well, thanks!

Do the assemblies come with bulbs? The description indicates they ship with 'test bulbs' which should be replaced. Just double-checking before buying bulbs as well.November 2, 2023

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.
