Nilight Third Brake Light High Mount Red Shell for Chevy Silverado & GMC Sierra

Enhance visibility with a bold red Nilight third brake light

Upgrade your truck’s signaling with a single, straightforward accessory. The Nilight Third Brake Light High Mount sits in a red shell that complements Chevy Silverado and GMC Sierra models equipped with cargo lights. Its full LED array includes 27 built-in diodes, with 9 dedicated to braking and 18 for the cargo light, delivering a crisp, immediate signal that blends safety focus with a clean, modern look.

Bright enough to catch attention

Compared with traditional halogen units, this LED assembly can shine up to ten times brighter, with fast activation that helps you communicate your braking status quicker. The result is a more noticeable signal to drivers behind you, without a heavy drain on your vehicle’s electronics over time.

• 27 LEDs total (9 brake, 18 cargo)
• Full LED source for consistent, long-lasting performance
• Up to 10x brightness compared to halogen equivalents
• Faster illumination enhances signaling in busy traffic

Weather-ready durability

The light is designed with an IP67 rating, meaning it resists water, snow, and dust while maintaining performance in varying climates. A high-density foam backing helps cushion the fit and contributes to a tight seal. For enhanced waterproofing, you can add a bead of butyl sealant around the fixture after installation.

Simple, tool-friendly install

Install in minutes with plug-and-play wiring—no drilling required. You can reuse factory screws for a precise, clean mount. For best results, a manual hand screwdriver is recommended to avoid over-tightening and potential cracking.

Fits your truck and use cases

This unit is compatible with Chevy Silverado and GMC Sierra models in the 1500/2500HD/3500HD families from 2014 through 2018, specifically those with cargo lights. While individual configurations vary, many owners appreciate the added brightness and a streamlined look when the light is illuminated.

Important notes

When evaluating compatibility, verify your cargo-light option and mounting locations. Results may vary by vehicle condition and installation approach; this upgrade offers a potential improvement in brightness and signaling, not a guarantee.
