Tresound LED Third Brake Light for 1988–1999 Chevy/GMC Trucks — Chrome Housing Smoked Lens with Cargo Lamp

Tresound's LED high-mount third brake light replaces the factory lamp on 1988–1999 Chevy and GMC C/K trucks and Silverado/Blazer models, delivering brighter stop signaling plus a built-in cargo lamp in a chrome housing with smoked lens.

This high-mount stop light is designed as a direct replacement for older GM trucks and SUVs, using long-life LEDs in a weatherproof ABS housing with a foam-mounted back gasket. It restores brake visibility while adding a subtle smoked appearance and a cargo lamp function so you can illuminate a truck bed or rear load area. The unit ships with mounting gasket hardware and is manufactured to meet strict quality checks so it fits and performs reliably.

Will this third brake light fit my 1988–1999 Chevy or GMC truck?

Yes—this lamp is engineered to match factory mounting points and electrical connections for specific years and models. It covers a broad set of GM pickups and some SUVs, so confirm your model and year before ordering.

• Compatible with 1988–2000 Chevy/GMC C1500, C2500, C3500 and K1500, K2500, K3500 models
• Fits 1992–1993 Chevy Blazer and 1994–1998 Chevy Silverado models
• Designed as a direct replacement—no major modifications required

How bright and durable are the LEDs compared with the original lamp?

The unit uses high-quality, super-bright LEDs that provide quicker illumination and improved visibility over incandescent bulbs. LEDs run cooler, consume less power, and have a longer rated life, reducing maintenance and bulb changes.

• Super-bright LED array for faster, clearer brake signaling
• Lower power draw and better heat management than traditional bulbs
• Manufactured under multiple quality-control checks for long-term reliability

Is the light weatherproof and suitable for heavy-duty use?

The housing is molded from ABS and includes a high-density foam-mounted back that forms a watertight seal against the vehicle. This prevents water, snow, and heavy rain from entering the assembly, protecting the LEDs and internal wiring.

• ABS housing resists cracking and UV exposure
• Foam-mounted back gasket blocks moisture and road spray
• Sealed construction suitable for daily driving and work environments

What additional features should I expect during installation and use?

Beyond brake signaling, the light includes a cargo lamp to illuminate the bed or rear loading area. It arrives with the necessary gasket and is shaped to align with factory screw locations so installation is straightforward for most DIYers or shops.

• Integrated cargo light for rear-area illumination
• Smoked lens with chrome housing for a clean, updated look
• Included gasket and standard mounting points for easy replacement

Who is this for: This Tresound LED third brake light is ideal for owners of 1988–1999 Chevy and GMC trucks and compatible Silverado/Blazer models who want improved rear visibility, a durable weatherproof assembly, and a subtle smoked aesthetic. It suits drivers who prefer an OEM-style replacement with upgraded LED performance—whether you use your vehicle for daily driving, work, or restoring an older truck.
