Cxdar Third 3rd Brake Light

The Cxdar Third 3rd Brake Light is a plug-and-play LED high-mount stop light with integrated cargo lamp designed to fit 1999–2007 Chevrolet Silverado and GMC Sierra models, offering brighter braking visibility and a low-profile smoke lens.

This LED center cab roof tail lamp combines an 8-red LED brake array with 10 white cargo LEDs in one compact housing. Built with an ABS shell, a sealed gasket and an IP65-rated lens, it resists rain, dust and snow to withstand daily road exposure. The light is tailored for a direct fit on specified Silverado and Sierra pickups, replacing the factory third brake light while adding modern LED performance and a smoked aesthetic.

Will this light fit my Silverado or Sierra?

Yes — the Cxdar third brake light is made for a range of full-size Chevy and GMC trucks from the model years listed. Confirm your truck model year and cab style before purchase to ensure a direct replacement without modification.

• Compatible: 1999–2006 Chevrolet Silverado & GMC Sierra 1500/2500; 2001–2006 Silverado/Sierra 1500/2500/3500 HD; 2007 Silverado/Sierra Classic models.
• Designed as a high-mount center cab roof lamp to match factory mounting points.
• Direct bolt-in with the original wiring harness in most vehicles.

How reliable is the light in wet or dusty conditions?

Engineered with an IP65 rating, the unit is protected against jets of water and limited dust ingress. The ABS housing and sealed gasket keep moisture and debris out of the LED chambers, helping the assembly last longer under typical driving conditions.

• IP65 waterproof rating for rain and road spray protection.
• Durable ABS housing and reinforced lens for impact resistance.
• Sealed cover and gasket to reduce corrosion and internal moisture.

What electrical or installation details should I know?

>The light is intended to be a plug-and-play replacement, but paying attention to a few electrical details will prevent problems. Do not fully tighten mounting screws at first to avoid cracking the housing; final torque after alignment is recommended. When used with LED cargo lamps, an LED hyper blink resistor may be needed in parallel with the bed/cargo light supply to maintain proper brightness and prevent hyper-flash conditions.

• Plug-and-play wiring for most compatible Silverado/Sierra models.
• Start screws by hand; do not fully tighten until alignment is confirmed.
• May require an LED hyper blink resistor for bed/cargo light brightness and flash control.

What lighting performance and features does it offer?

>This combo lamp delivers clear signaling plus practical cargo illumination using energy-efficient LEDs. The dual-row configuration uses 8 red LEDs for brake/stop visibility and 10 white LEDs for cargo-area lighting, offering improved response time over incandescent bulbs and lower power draw.

• 8 red LEDs for high-mount brake/stop signaling.
• 10 white LEDs to illuminate the bed or rear cargo area.
• Low power consumption and long LED lifespan compared to bulbs.

Who this is for: This Cxdar high-mount brake and cargo lamp suits Silverado and Sierra owners who want a factory-fit LED upgrade with a smoked lens and durable construction. It's ideal for drivers replacing a failed third brake light, looking to modernize older trucks with LED efficiency, or anyone needing improved rear brake visibility and cargo illumination while maintaining a near-stock appearance.
