Tresound Third Brake Light for 1988–1999 Chevy/GMC C/K Trucks — Chrome Housing Smoked Lens, Bright LED

Tresound's LED third brake light replaces the high-mount stop lamp on 1988–1999 Chevy and GMC C/K trucks and Blazers with a sealed, high-visibility smoked-lens unit. This high-mount stop lamp combines a polished chrome housing with a smoked lens and bright LED array to update the rear visibility and cargo illumination of older Chevy and GMC trucks. Built from durable ABS with a foam-mounted backing gasket, the lamp resists moisture and vibration while fitting the factory mounting points for a straightforward swap. It restores both the brake-light function and a cargo light feature, maintaining the truck's original look while improving reliability and brightness.

Will this third brake light fit my truck?

Compatibility covers a wide range of classic Chevy and GMC pickups and SUVs. The lamp is designed to match factory mounting locations for the listed model years, so installation typically requires no modification when your vehicle is within the stated fitment range.

• Fits 1988–2000 Chevy/GMC C1500, C2500, C3500 and K1500, K2500, K3500 series
• Compatible with 1992–1993 Chevy Blazer and 1994–1998 Chevy Silverado
• Uses stock mounting points and wiring harness in most applications
• Check exact year/model fitment before ordering to ensure correct alignment

How durable and weatherproof is the unit?

The housing is molded from impact-resistant ABS and includes a high-density foam-mounted back that creates a tight seal against the truck's body. That combination helps keep out rain, snow, and road spray so the LEDs can perform reliably over time.

• ABS housing resists cracking and UV deterioration
• Foam-mounted gasket reduces water intrusion and wind noise
• Sealed LED assembly minimizes failure from moisture
• Made to withstand vibration common on trucks and off-road use

What lighting functions and brightness can I expect?

The assembly includes a focused LED array serving as the high-mount stop light plus a cargo illumination function to light the bed area. LEDs offer quicker illumination than incandescent bulbs and deliver bright, consistent light output for improved visibility.

• Super-bright LEDs for clear brake signaling
• Integrated cargo light to illuminate the truck bed when needed
• Smoked lens for a subdued factory-style appearance without sacrificing output
• Chrome housing for a clean, period-correct finish

How simple is installation and what comes in the box?

Installation is intended to be bolt-on for compatible trucks and ties into the existing brake light wiring. The lamp ships with a gasket for a sealed fit and follows Tresound’s quality checks, reducing the chance of missing parts or defects out of the box.

• Included high-density foam gasket for a sealed mounting surface
• Plug-and-play wiring for most factory harnesses; adapter may be required in rare cases
• Standard hardware for mounting to original locations
• Multiple quality-control inspections during manufacturing

Who is this for This LED third brake light is aimed at owners of late-80s and 90s Chevy and GMC trucks and SUVs who want a reliable, weather-resistant replacement that preserves the vehicle’s original appearance while upgrading to long-lasting LEDs. It’s a good choice for restorers, daily drivers, and those who need dependable cargo illumination and improved rear signaling without custom fabrication.
