Cxdar Third Brake Light LED for 2014–2018 Silverado/Sierra — Center Cargo Lamp, IP67 Waterproof

Cxdar's Third Brake Light LED is a direct-replacement high-mount stop lamp designed for 2014–2018 Chevy Silverado and 2015–2018 GMC Sierra trucks with the factory cargo light configuration.

This high-mount LED brake light assembly combines durable OE-grade materials with a weatherproof design and simple installation to restore or upgrade your truck's center rear stop lamp. Built with a tough ABS housing, a polycarbonate lens, and IP67 sealing, the unit resists moisture, dirt, and road debris while delivering bright, low-power illumination. It’s intended as a compatible aftermarket replacement for specific Silverado and Sierra models—confirm fitment before purchasing.

Which truck models and years will this brake light fit?

This Cxdar center cab stop light fits 2014–2018 Chevrolet Silverado 1500 and 2015–2018 Chevrolet Silverado 2500HD/3500HD and corresponding GMC Sierra models that were factory-equipped with a cargo light. Note one important exception: it does not fit the 2014 Silverado 2500HD/3500HD. Always verify your truck’s year and cargo-light option prior to ordering to ensure compatibility.

• Compatible: Chevy Silverado 1500 (2014–2018)
• Compatible: Chevy Silverado 2500HD/3500HD (2015–2018) with cargo light
• Compatible: GMC Sierra equivalents for the same model years
• Not compatible: 2014 Silverado 2500HD/3500HD

How durable and weatherproof is the Cxdar third brake light?

The assembly uses OE-grade ABS for the housing and a polycarbonate (PC) lens that resists acids, alkalis, and impact. With high-density foam mounting and IP67-rated sealing, it protects internal LEDs from rain, mud, snow, and dust, making it suitable for typical on-road and off-road conditions.

• Housing: OE-grade ABS for structural strength
• Lens: Polycarbonate—chemical and impact resistant
• Sealing: IP67 waterproof rating with foam gasket
• Longevity: Low power consumption for extended LED life

Is installation difficult and will I need extra parts?

Installation is designed to be straightforward: the lamp uses the truck’s existing bolt holes for mounting and connects to the factory wiring. In most cases it’s plug-and-play, but some vehicles may require a simple harness pin modification to match the connector—no cutting of the housing required. If you’re comfortable with basic wiring or a quick modification, the swap can be completed at home.

• Mounting: Uses existing bolt holes—no new drilling
• Wiring: Typically plug-and-play; harness pin may need adaptation
• Tools: Basic hand tools and possibly small wiring tools
• Support: Manufacturer support available for installation questions

What performance and safety features should I expect?

The LED assembly delivers bright, consistent stop-light illumination while consuming less power than incandescent bulbs. Because it’s centered and mounted high on the cab, it enhances visibility to drivers behind your truck. The construction reduces the chance of failure from water ingress or impact, contributing to reliable operation over time.

• Lighting: High-visibility LED stop lamp output
• Energy: Low power draw extends component life
• Protection: Sealed design limits moisture and debris intrusion
• Warranty: Customer support and warranty assistance available

Who is this for: Truck owners who need a durable, weatherproof replacement or upgrade for the center high-mount stop lamp on compatible 2014–2018 Chevy Silverado and 2015–2018 Silverado 2500/3500 or matching GMC Sierra models with the cargo light option. It’s suited to DIY installers who want a mostly plug-and-play solution but are prepared to adapt a harness pin if necessary. If your truck is a 2014 Silverado 2500HD/3500HD, this model is not compatible—please verify fitment before purchasing.
