Partsam High Mount LED Third Brake Light for 2007-2013 Silverado/Sierra — Smoke Lens, White Cargo Lamps

Partsam's High Mount LED third brake light is a direct-fit replacement for 2007–2013 Silverado and Sierra trucks that restores center roof/cargo illumination with a smoke lens and bright, long-lasting LEDs.

Whether you're replacing a cracked factory lens or upgrading to a more modern LED assembly, this Partsam unit is designed to match the original mounting points and electrical connectors used on Silverado 1500 and Sierra 1500 models as well as the 2500HD and 3500HD line through model year 2013 (with fitment notes for some 2014 heavy-duty models). It combines an LED stop lamp with white cargo illumination under a smoked lens and includes a foam gasket for improved sealing.

How do I know this will fit my Silverado or Sierra?

This assembly is engineered to replace the center high-mount stop light used on 2007–2013 Chevrolet Silverado and GMC Sierra models, including most 1500, 2500HD and 3500HD variants. It follows factory hole locations and connector style so installation is straightforward for common applications.

• Compatible model years: 2007–2013 Silverado and Sierra 1500, 2500HD, 3500HD.
• Replacement part numbers often cross-referenced: 25890530, 531066, 531067.
• Notes: many 2014 2500HD/3500HD trucks use this style as well—confirm with your vehicle.

What functions and light modes does the unit provide?

The light supplies a bright red LED stop lamp and two white cargo/courtesy lamps beneath a smoked lens. Red LEDs illuminate with braking, while the white lamps operate with the vehicle’s interior/cargo light circuit rather than as reverse lights.

• Full LED stop light for improved visibility and longer service life compared with incandescent bulbs.
• White cargo lights activate with the dome/cargo light switch, not automatically with door open.
• Outer white LEDs are cargo/courtesy lights, not reverse lamps.

How difficult is installation and how weatherproof is it?

Installation is intended to be simple: remove the old assembly, clean the mounting surface, and secure the new lamp. Partsam supplies a foam gasket to reduce water intrusion, but users are advised to add a bead of silicone or clear RTV where wires and seams meet for extra protection.

• Includes 1 foam gasket; screws are not included—reuse factory screws for proper fit.
• Recommended: clean the gasket area with alcohol before mounting for best seal.
• Apply silicone/RTV across the top edge and wire entry to improve waterproofing.

Will this change the look or electrical behavior of my truck?

The smoked lens and black housing give the rear a more modern, slightly stealthy appearance while maintaining all factory light functions. Because LEDs are used, you’ll get a crisper, more consistent illumination pattern and you won't need to worry about incandescent bulbs burning out.

• Modernized appearance with smoke lens and black housing styling.
• LEDs provide consistent brightness and long-lasting operation versus bulbs.
• Cargo lights only operate with the dome/cargo switch—behavior mirrors OEM replacement units.

Who is this for: Drivers and technicians who need a reliable, OEM-style replacement for a damaged or worn high-mount center brake/cargo lamp on 2007–2013 Chevy Silverado and GMC Sierra trucks. It’s also a practical upgrade for owners wanting LED longevity and a darker lens aesthetic, provided they can reuse the original mounting screws or have replacements on hand.
