Partsam High Mount LED Third Brake Light for 2007–2013 Silverado/Sierra — Smoked Lens with White Cargo LEDs

Partsam's High Mount LED third brake light replaces the factory rear cab roof center lamp on 2007–2013 Chevy Silverado and GMC Sierra trucks with a smoked lens and bright, long-lasting LEDs.

Upgrade your truck's rear signaling and cargo lighting with a direct-fit LED third brake light designed to match the 07–13 Silverado 1500/2500/3500 and Sierra 1500/2500/3500 roof center lamp openings. This replacement uses sealed LEDs in a black housing and smoke lens to modernize appearance, reduce bulb failures, and restore both brake and cargo illumination. The unit ships with a foam gasket and requires reuse of the original mounting screws; adding sealant over seams improves long-term water resistance.

Will this LED third brake light fit my Silverado or Sierra?

Yes — the Partsam lamp is built to fit the roof center cavity for Chevrolet Silverado and GMC Sierra models from 2007 through 2013, and it also replaces certain 2014 heavy-duty center stop lights. It is compatible with 1500, 2500HD and 3500HD model lines that use the same high-mount arrangement.

• Direct-fit for 2007–2013 Silverado/Sierra 1500, 2500HD, 3500HD.
• Listed replacement part numbers include 25890530, 531066 and 531067.
• Works as replacement for some 2014 2500/3500 center mount stop lights.
• Reuses factory screws — save them during removal.

How does the light perform and what functions does it have?

This LED assembly offers bright red brake illumination plus white cargo/utility lights controlled by the truck's interior light circuit. LEDs reduce maintenance versus incandescent bulbs and provide a consistent output. Note: the two outer white LEDs are cargo lights tied to the interior dome switch, not reverse lamps.

• Super-bright full LED array for brake signaling.
• White cargo lights activate with interior/dome light control.
• Outer white LEDs do not operate as reverse lights.
• Cargo lights do not automatically trigger on door open unless interior lights are set to on.

What do I need for installation and sealing?

Installation is straightforward: remove the old lamp, clean the gasket channel, position the new light with the included foam gasket, and reinstall using the truck’s original screws. For improved waterproofing, apply a thin bead of silicone or clear RTV across the top seam and around the wiring exit to prevent leaks.

• Includes 1 foam gasket; screws are not included — reuse factory screws.
• Clean mating surfaces with alcohol before seating the gasket.
• Use rubber washers to seal screw penetrations if available.
• Add silicone/RTV across seams for extra water protection.

Is this light weatherproof and durable?

The Partsam third brake light is built with a sealed housing and foam gasket to resist moisture intrusion during normal use, but spot-sealing with silicone is recommended for longer life in wet climates. The black housing and smoke lens also resist yellowing and give a modern, low-profile look that complements late-model trucks.

• Foam gasket provided to help seal against the roof opening.
• Recommend extra RTV or silicone application at seams and wiring exit.
• Durable black housing and smoke lens for contemporary styling.
• LEDs eliminate filament burnout concerns common with incandescent bulbs.

Who is this for? If you own a 2007–2013 Chevrolet Silverado or GMC Sierra and need a reliable, direct-fit replacement for the roof-mounted center brake/cargo lamp — or you want to update an aging incandescent unit to an LED assembly with a smoked lens — this Partsam third brake light delivers a straightforward swap, improved illumination, and a refreshed rear appearance. Ideal for owners doing a repair, restoration, or visual upgrade who can reuse the factory fasteners and are prepared to apply a small bead of sealant for maximum water resistance.
