Nilight LED Third Brake Light for Chevy GMC C/K Series 1994–2000 — Cargo Light, IP67 Weatherproof

Nilight's LED third brake light is a direct-fit LED replacement for Chevy and GMC C/K Series trucks (1994–2000) that combines brighter stops, integrated cargo illumination, and weatherproof durability.

Replace the factory halogen center high-mounted stop lamp with a modern LED module built to match original mounting points while delivering quicker, more visible signaling and an added cargo light. This Nilight assembly is made to align with the cargo-light variant of the C1500/C2500/C3500 and K1500/K2500/K3500 trucks from model years 1994 through 2000 and uses the same screw locations for an easy swap.

Will this third brake light fit my Chevy or GMC truck?

Yes — this Nilight unit is designed to fit the cargo-light version of Chevy and GMC C/K Series trucks from 1994 to 2000. It replaces OEM part numbers 16521970 and 15030176 and installs into the original opening without trimming or drilling.

• Compatible models: Chevy/GMC C1500, C2500, C3500, K1500, K2500, K3500 (1994–2000) with cargo light function.
• Replaces factory part numbers 16521970 and 15030176.
• Uses existing factory screw locations for a plug-and-play swap.

How much brighter and faster is the LED unit compared to the stock lamp?

This LED replacement features a full-LED array with 26 diodes — 14 dedicated to the brake function and 12 for cargo illumination — producing far greater brightness and faster illumination than a halogen bulb. Faster light-up improves reaction time for drivers behind you, while higher output enhances visibility in daylight and poor weather.

• 26 built-in LEDs: 14 brake LEDs and 12 cargo LEDs for clear signaling and work-area lighting.
• Significantly brighter than halogen; lights up faster to improve noticeability.
• Energy-efficient design for long operating life compared to OEM halogen.

Is the light weatherproof and durable for daily driving?

The housing is engineered for outdoor use and sealed with a high-density foam pad to prevent moisture intrusion. The product meets IP67-level protection, so it resists dust and temporary immersion, but for best long-term sealing you should apply butyl sealant around the fixture after installation.

• IP67-rated sealing to resist water and dust infiltration during wet conditions.
• High-density foam backing included for an improved factory-style seal.
• Recommended: add butyl sealant after install for maximum waterproofing.

How difficult is installation and what hardware is included?

Installation is straightforward: the Nilight lamp is plug-and-play and uses the truck's original screw points so you won’t need to drill. The package includes the LED assembly and the foam pad; use the factory screws and hand tools to avoid over-tightening and cracking the housing.

• Plug & play connector—no wire splicing required for most correct cargo-light variants.
• Includes 1 LED third brake light and 1 high-density foam pad.
• Use original factory screws and a hand screwdriver for proper fitment.

Who is this for: This Nilight LED third brake light is aimed at owners of 1994–2000 Chevy and GMC C/K Series trucks who want a direct replacement that improves stop-light visibility and adds a reliable cargo/work light. It's ideal for DIY installers who prefer a bolt-in upgrade using original mounting points, as well as fleet owners wanting a longer-lasting, energy-efficient alternative to OEM halogen units.
