Cxdar LED Third Brake Light for 1999–2007 Silverado/Sierra — Smoke Lens, Dual‑Row LEDs & Cargo Light

The Cxdar Third 3rd Brake Light is a direct-replacement LED high‑mount stop lamp with integrated cargo lighting and a smoke lens, built to fit 1999–2007 Chevrolet Silverado and GMC Sierra trucks.

This high-mount LED assembly combines a bright red brake lamp with white cargo illumination in a single, weather‑resistant housing. Designed to match the factory mounting points for Silverado and Sierra models specified below, it uses low-power dual‑row LEDs to modernize rear visibility while resisting water, dust, and snow thanks to an IP65-style seal and durable ABS construction.

Will this third brake light fit my Silverado or Sierra?

The Cxdar third brake light is engineered for direct compatibility with specified model years and trims. It fits 1999–2006 Chevrolet Silverado and GMC Sierra 1500/2500, 2001–2006 Silverado/Sierra 2500/3500HD, and 2007 Silverado/Sierra Classic models when used with original mounting points.

• Fits 1999–2006 Chevy Silverado & GMC Sierra 1500/2500.
• Compatible with 2001–2006 Silverado/Sierra 2500/3500 HD.
• Works for 2007 Silverado/Sierra Classic models.
• Designed to replace OEM high‑mount lamp without major body modification.

How bright and efficient is the LED assembly?

Light output is split between eight red LEDs for brake signaling and ten white LEDs for cargo illumination. The dual‑row LED layout delivers clear, energy‑efficient lighting that improves nighttime visibility while drawing minimal current.

• 8 red LEDs for brake/stop indication.
• 10 white LEDs for bed/cargo lighting.
• Low power consumption extends vehicle electrical life.
• Dual‑row design for even light distribution.

Is the light durable and weatherproof for daily truck use?

The lamp uses a rugged ABS housing and a solid lens with a sealed gasket to raise resistance against water, dust, and snow exposure. The IP65‑style protection and sturdy construction help extend service life under normal highway and worksite conditions.

• ABS housing resists impact and UV fading.
• Well‑sealed gasket prevents moisture ingress.
• Smoke lens for a subtler factory look while protecting LEDs.
• Rated to withstand rain, dirt, and light snow exposure.

How straightforward is installation, and any wiring notes?

Installation follows a plug‑and‑play approach with existing factory connectors and mounting points; hand fastening first is recommended to avoid cracking the case. For trucks with LED bed/cargo lights, add an LED hyper blink resistor in parallel across the cargo light feed so the cargo LEDs illuminate at full brightness.

• Plug-and-play with factory harness on compatible models.
• Hand‑screw initial fasteners before final tightening.
• May require LED hyper blink resistor for bed/cargo lighting compatibility.
• Professional installation recommended if unsure about wiring.

Who is this for: The Cxdar Third Brake Light is ideal for Silverado and Sierra owners (1999–2007 specified models) who want an upgraded OEM‑style high‑mount light with integrated cargo illumination, improved LED efficiency, and enhanced weather protection. It suits drivers replacing a damaged factory lamp or upgrading to a modern LED assembly for better night‑time cargo visibility and a refreshed rear appearance.
