Hi, I'm Mike Green. I'm one of the owners of 1A Auto. I want to help you save time and money repairing or maintaining your vehicle. I'm going to use my 20-plus years experience restoring and repairing cars and trucks like this to show you 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 replace the taillight, either replace the taillight bulb or the procedure for replacing the entire tail light. The only tool you'll need is a 10mm wrench or a socket wrench with ratchet and maybe a pair of pliers and a flat-blade screwdriver.
Starting with your tailgate, open there are two 10mm bolts on each side for each light. You want to remove those 10mm bolts. We'll just kind of speed through removing those. You can use a 10mm wrench or a socket and ratchet like I have.
Once you have those bolts out, pull it firmly. If you're looking to just change your bulbs, turn them counterclockwise. The socket comes out. The bulbs just pull out of the sockets. Your harness goes down into there. Up underneath you want to unplug your connector. There's a tab right here. You press and unplug. Then the connector is held onto the frame. You have to pull it off. Then this clip here that holds the harness on, you pull that off as well. You can get that from 1A Auto. It comes with everything including a harness and plug.
You see my old light is perfectly fine. I'm not going to go through all that changing out of the harnesses and stuff. To reinstall, I'll move it into place and make sure these tabs go into here and then down there as well. We'll fast-forward again as I thread those bolts in by hand first. I might have to push on the light a little bit to get the holes to line up. Tighten them up with the socket by hand. Then tighten them up firm with the ratchet.
We hope this helps you out, brought to you by www.1AAuto.com, your source for quality replacement parts and the best service on the internet. Please feel free to call us toll free 888-844-3393. We're the company that's here for you on the internet and in person.

I replaced my 14 year old lens that were in sad shape. Slapped these puppies on and "Bam"!, Instant bright lights. Exact fit, bulb placement was a little tight but I was able to work them in.
Excellent fit

These look exactly like the originals and make the taillights/turn signals very visible again. Only complaint is the fit is a bit off on the driver's side (it sticks out a little more than the OEM). Not a big deal for me, but it's obvious it's not a factory original.

I bought these expecting them not to fix exactly as described. I was wrong. It took maybe 5 minutes to install these and my truck tail lights look brand new. The lens fit and look just like OEM.
Very pleased with this purchase.
