Think TechSmart First: Complete Kit
The Problem: When the gasket on an OE third brake light dries out and cracks, it can allow water to leak into the cab. Over time, the buildup of moisture in the lens housing can cause the high-mount stop lamp to fail.
Our Response: As a premium replacement part, TechSmart’s Third Brake Light features a brighter LED than its OE counterpart and comes complete with an OE-matching, molded rubber gasket. The part has applications for select GMC Yukon and Chevrolet Tahoe and Suburban models. If you only need to replace the gasket instead of the light, check out TechSmart's S47002 Third Brake Light Gasket.
