Anzo USA 311090 GMC Sierra Black LED Tail Light Assembly Pair - Durable Replacement for Enhanced Night Visibility & Safety | Perfect for Off-Roading, Towing & Daily Driving

I am very happy with these taillights. They look very sharp on my 2008 Sierra Denali. I ended up customizing them to my liking. These lights have a red border around the outside and my stock taillights on my Sierra have a black border. So I sprayed them with 3 coats of black automotive gloss spray paint and I couldn't be happier with how they turned out! The only issue that I had on my install was that the holes for the prongs on my truck were not large enough to accommodate the Anzo prongs. An easy fix though. I removed my prongs off my stock taillights and screwed them into the Anzo lights. I added a little locktite to keep it from backing out. The lights come with new a new wiring harness but is really not necessary as you can use your factory harness. IF YOU USE YOUR FACTORY HARNESS, PULL THE O-RINGS OFF OF THE NEW HARNESS. The o rings that come on the new wiring harness are a hair thicker and will ensure that moisture stays out of your new taillights. I am very happy with my purchase and would highly recommend these lights on your GM truck.
