Review on VIPMOTOZ Third Brake Light Stop Lamp Gasket - 1999-2006 Chevy Silverado GMC Sierra 1500 🔧 2500HD 3500HD Pickup Truck - Upgrade 4mm Thickness Seal Replacement Foam - Double Side Ultra Strong Adhesive by Kenneth Cotton

This seal was replaced on my 16 year old truck after I saw a drip on the rear window when it was raining. The old one was crusty and required some scraping to remove. The new one comes with a strong center to keep its shape. Align it with the design of the edges and glue it to the back of the lamp. My lamp is getting old and brittle, but it didn't break and was a lot cheaper than a new lamp. As for the leak. I chased the water along the doors behind the front seat. This water was actually leaking out of the cockpit vents, which were cracked around the edges. So if you are chasing water, the central light is just one of the points to check. More than a month has passed and there were no more drops on the central headlight.
