How durable and weatherproof is the Cxdar LED brake light?

The housing uses OE-grade ABS and the lens is crafted from high-quality polycarbonate to resist impacts, UV, and chemical exposure. A high-density foam mounting gasket and IP67-rated sealing prevent intrusion from rain, snow, and road grime, helping maintain reliable illumination in harsh conditions.

• Materials: OE-grade ABS housing, PC plastic lens for toughness.
• Sealing: IP67-rated protection against water and dust.
• Mounting: foam gasket reduces vibration and seals the body opening.
• Longevity: low power LEDs for extended service life and energy efficiency.

Is installation difficult and will it require wiring changes?

Installation is designed to be straightforward: the light uses the vehicle’s existing bolt pattern for a bolt-in replacement and plugs into the truck’s wiring harness. In many cases it is plug-and-play; however, some vehicles may require minor pin or harness adjustments to match connectors.

• Mounting: uses existing bolt holes—no body drilling required.
• Electrical: typically plug-and-play; verify connector pinout on arrival.
• Tools: basic hand tools recommended for removal and installation.
• Note: if harness pins differ, slight connector modification may be necessary.
