Cxdar Third 3rd Brake Light LED for 2014-2018 Chevy

The Cxdar LED third brake light is a direct-fit high-mount stop lamp engineered for 2014–2018 Chevy Silverado and 2015–2018 GMC/ Silverado HD trucks to restore center-cab cargo lighting and improve rear visibility.

This high-mount stop lamp replaces the factory center cargo/stop light assembly on compatible Silverado and Sierra pickups. Constructed from impact-resistant materials and sealed for weather protection, the unit uses bright, low-draw LEDs and installs using the truck’s existing mounting points for a near plug-and-play swap. It’s designed for owners needing a rugged replacement that withstands road grime, rain, and snow while keeping electrical draw minimal.

Will this lamp fit my Silverado or Sierra model?

Compatibility covers most late-model short- and heavy-duty models but varies by year and whether the truck originally had a cargo light. Confirm the vehicle year and the presence of the cargo/center light before ordering to ensure proper fitment. Note that some 2500/3500HD 2014 models are excluded.

• Fits: 2014–2018 Chevy Silverado 1500 models with cargo light
• Fits: 2015–2018 Chevy Silverado/GMC Sierra 2500HD and 3500HD when original cargo light present
• Does NOT fit: 2014 Silverado 2500HD/3500HD (verify before purchase)

How durable is the Cxdar third brake light in harsh conditions?

The assembly uses OE-grade ABS and a polycarbonate lens that resist impacts, UV, and common road chemicals. A high-density foam gasket and IP67-level sealing keep moisture and contaminants out, helping the light last through heavy rain and winter conditions.

• Lens: acid- and alkali-resistant polycarbonate for toughness
• Housing: OE-grade ABS built to resist weathering and impacts
• Seal: high-density foam and IP67-rated waterproofing against dust and water

What should I expect during installation?

Installation is straightforward for most owners: the light uses the truck’s existing bolt locations for mounting so you won’t need to drill new holes. Most installs are plug-and-play, though some harness pins may require minor modification to match your truck’s connector.

• Mounting: uses original bolt holes—no major modifications required
• Electrical: typically plug-and-play; check connector pinout before finalizing
• Tools: common hand tools suffice for removal and reinstallation

What kind of performance and maintenance can I expect?

The LED array delivers bright, consistent illumination with low power consumption and minimal upkeep compared with incandescent units. Routine care is limited to occasional cleaning of the lens and inspection of the gasket to preserve the waterproof seal.

• Lighting: bright LEDs for clear center brake indication
• Power: low consumption extends vehicle electrical life
• Maintenance: clean lens periodically and check seal for debris

Who is this for: The Cxdar third brake light is intended for owners of compatible 2014–2018 Chevy Silverado and 2015–2018 Silverado/GMC Sierra HD trucks who need a rugged, weatherproof replacement for their center high-mount stop lamp. It’s a good choice for drivers who value durability, straightforward installation, and efficient LED illumination for towing, hauling, or daily driving. Confirm fitment with your truck’s model year and cargo light configuration before purchase.
