Tail Lights for 2001 GMC Sierra 1500.
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.

I ordered these to replace my old, yellowed, scratchy lights. They are a perfect fit, and make my pickup look new again. Great price, and great look.

Replacement lights
These lights are not molded correctly to fit my turn signal sockets so I returned them and are waiting for a refund. I would hav preferred a referral to a place to purchase the correct ones.

Great replacement product!
I bought these to replace some aftermarket lights the previous owner had installed. They were hard to see and just didnt 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!
