LESAUCE LED 3rd Brake Light for 1999–2006 Chevy Silverado & GMC Sierra — Chrome Housing, White Cargo Lights

LESAUCE's 2025 upgraded third brake light is a direct-fit LED high-mount stop lamp designed to replace the factory unit on 1999–2006 Chevrolet Silverado and GMC Sierra trucks, giving brighter braking visibility and built-in cargo illumination.

This high-mount stop light swaps into place of the original lamp on compatible Silverados and Sierras and combines full LED illumination with a chrome housing and red lens for modern looks and improved longevity. It preserves the truck's factory mounting points while adding white cargo lights that turn on with the dome, plus a foam gasket for basic waterproofing and included rubber washers to secure the lens.

Will this third brake light fit my Chevy Silverado or GMC Sierra?

Yes — this LESAUCE unit is engineered as a direct replacement for specific model years and trims. Verify your truck’s year and model before ordering to ensure a correct fit without modifications.

• Compatible with 1999–2006 Chevrolet Silverado 1500/2500/3500 models
• Fits 2001–2006 Chevrolet Silverado 1500HD/2500HD/3500HD and 2007 Silverado HD Classic
• Also fits 1999–2006 GMC Sierra 1500/2500/3500 and 2001–2006 Sierra HD variants
• Designed to use your truck’s original screw locations (retain factory screws)

How does the LED design improve performance over the stock bulb?

The full LED array delivers brighter, more consistent light than incandescent bulbs and resists fading and burn-out. LEDs consume less power and light up quicker, improving visibility for following drivers and lasting far longer than traditional bulbs.

• Super bright full LED stop lamp for clear brake signaling
• Chrome housing and red lens for a modern aesthetic and contrast
• Lower power draw and longer operational life than incandescent lamps
• White cargo lamps illuminate with dome lights for rear bed visibility

Is installation difficult and what hardware is included?

Installation is straightforward for anyone familiar with basic truck maintenance: clean the mounting lip, reuse the factory screws, and seat the light with the supplied rubber washers. LESAUCE includes a foam gasket for general sealing but recommends additional silicone for maximum waterproofing.

• Simple bolt-in fit using original screw locations (original screws not included)
• Rubber washers provided to prevent vibration and secure the lens
• Foam gasket included for initial waterproofing; optional RTV/silicone recommended
• White cargo lights operate with dome light; outer whites are not reverse lamps

What should I expect in daily use and maintenance?

Expect consistent brake-light performance and occasional cleaning to keep the lens clear. The LEDs require little upkeep, but checking the gasket and resealing if necessary will help maintain weather resistance over time.

• Bright, reliable brake signaling in varied lighting conditions
• Cargo illumination available when interior lights are active
• Periodic visual check of the gasket and silicone seal to prevent leaks
• Retain original mounting screws; replace if corroded to keep a secure fit

Who is this for? This LESAUCE third brake light is for Silverado and Sierra owners (listed years above) who want a direct-fit LED upgrade that improves rear signaling, refreshes the truck’s appearance, and adds cargo lighting without complicated wiring changes. It’s a good choice for drivers seeking durable, energy-efficient illumination that preserves factory mounting points while providing a modern look.
