Nilight LED Third Brake Light for Chevy GMC Silverado Sierra 2014–2018, Smoked — 27-LED, IP67

This compact LED third brake light replaces the factory cargo light style on compatible Silverado and Sierra models, delivering improved visibility, quicker activation and a low-profile smoked lens. Manufactured to OEM-grade standards, the unit contains 27 integrated LEDs (9 brake, 18 cargo) and includes a high-density foam pad for a sealed fit. It’s designed for models equipped with cargo lights only and installs without drilling using original hardware for a secure, neat finish.

Which trucks is this Nilight third brake light compatible with?

This brake light is tailored for select Chevy and GMC pickup models produced between 2014 and 2018. It fits vehicles that came from the factory with cargo light-style third brake lights—not universal mounts.

• Chevrolet Silverado 1500: 2014–2018
• Chevrolet Silverado 2500HD & 3500HD: 2015–2018
• GMC Sierra 1500: 2014–2018
• GMC Sierra 2500HD & 3500HD: 2015–2018

How does the LED upgrade improve braking visibility?

The built-in LEDs illuminate faster and brighter than traditional halogen bulbs, giving drivers behind more reaction time. The light uses separate circuits for brake and cargo functions so the stop lamp and area illumination remain distinct and effective.

• 27 total LEDs: 9 for brake, 18 for cargo lighting
• Faster illumination than halogen for quicker visual cueing
• Higher lumen output for improved daytime and nighttime visibility

Is the unit weatherproof and durable for outdoor use?

The housing ships with a high-density foam pad and sealed construction that meets IP67 standards, protecting the LEDs from water, dust and road grime. After installation, applying butyl sealant around the perimeter is recommended to ensure long-term waterproofing in harsh conditions.

• IP67-rated sealing against water and dust ingress
• High-density foam pad included for a snug, vibration-resistant fit
• Durable OE-grade materials and LED components for extended life

How difficult is installation and what’s in the box?

Installation is plug-and-play with no drilling required; the product is designed to use your factory screws and wiring harness. Use a hand screwdriver to avoid overtightening and cracking the housing — electronic tools can apply too much torque.

• Includes: 1 LED third brake light and 1 high-density foam pad
• Plug-and-play wiring — connects to existing factory harness
• Recommended to reuse factory screws; hand-tool installation advised

Who this is for: truck owners who want a straightforward, OEM-friendly improvement in rear visibility and styling. If you drive a compatible 2014–2018 Silverado or Sierra with a cargo-style third light and prefer a smoked, low-profile appearance without cutting or major wiring changes, this Nilight LED module gives a brighter, longer-lasting upgrade that installs quickly and holds up in wet weather when sealed properly.
