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.

The tail lights fit in the truck bed OK; however, the center slots in each tail light had to be modified in order to receive the light sockets. Unfortunately, the notches did not line up exactly and the holes were a little small. I was expecting them to fit exactly but I was able to modify them enough with a small file to get the sockets in place. At $94.95 for 2 tail light lens they should have fit right out of the box.

Tail lights arrived with an incorrect bulb socket. 1A researched the problem and wasn't able to fix. It was a manufacturer defect. Offered a full refund. Very satisfied, will buy from again.

I bought these to replace some aftermarket lights the previous owner had installed. They were hard to see and just didn't look good on the truck. The new ones came well packaged. They installed easily and the fit was as good as I would expect from OEM. The quality is OEM too. The new ones are bright and look great on this truck. Price was awesome too!
Beautiful set , Perfect fit !

The OEM tail lights have locking tabs for all 3 light sockets, these do not have a locking tab for the amber light, The socket seems to seat ok so I kept them. New Light assemblies sure make a truck look better.

I have taken very good care of my 03 Sierra and it does not look like a 17 year old truck. But all the Exterior lights were showing their age. Last year I bought all new lights for the front and finally replaced the rear lights last month. What a huge difference! The new lights really make it look a few years younger. Plus my old lights werent as bright because the plastic had discolored. But theses new ones are clear and bright. Definitely recommend!

I was extremely satisfied with the products I ordered. They all arrived in excellent condition and was shipped and delivered very fast.
One suggestion. As with any older truck their is rust on it and the screws needed to be broke off the old tail light. Maybe add an option to include new screws for the tail lights when the order is placed. Was not a big deal, just a ride to the hardware store. Lol
