Nilight Third Brake Light for Chevy/GMC C/K Series 1994–2000 — Cargo Light LED, Plug-and-Play

Nilight's LED third brake light is a plug-and-play replacement for Chevy and GMC C/K Series (1994–2000) that combines 26 high-output LEDs for brighter, faster signaling and an integrated cargo light for added utility.

If your pickup's center high-mounted stop light has dimmed, failed, or you simply want a more visible, longer-lasting option, this Nilight unit upgrades the factory halogen lamp with modern LED performance. Designed to match OEM fitment for C1500/C2500/C3500 and K1500/K2500/K3500 trucks from 1994 through 2000 (models equipped with the cargo light function), it installs without drilling and uses the existing mounting points for a clean, factory-style finish.

Will this third brake light fit my Chevy or GMC C/K Series truck?

Yes, this Nilight brake light is built to replace the original cargo‑light version on 1994–2000 Chevy and GMC C/K Series pickups. It matches common OEM part numbers for direct swap compatibility.

• Compatible trucks: C1500, C2500, C3500, K1500, K2500, K3500 (1994–2000).
• Replaces part numbers: 16521970 and 15030176.
• Only fits trucks originally equipped with the cargo light function.
• Uses factory screws and mounting holes—no new drilling required.

How much brighter and faster are the LEDs compared with the original bulb?

The Nilight assembly uses 26 integrated LEDs—14 dedicated to the brake lamp and 12 for the cargo light—so it illuminates much more quickly and noticeably than a halogen bulb. Brighter, faster light improves rearward visibility and reaction time for drivers behind you.

• 26 high-output LEDs provide stronger, uniform light.
• LEDs light up faster than halogen, improving noticeability.
• Estimated to be several times brighter than original halogen units.
• Longer operational life and higher energy efficiency than bulbs.

Is the light weatherproof and durable for regular truck use?

The housing includes a high-density foam gasket and thorough sealing to resist water intrusion, keeping the LEDs working in wet or snowy conditions. For best protection, a bead of butyl sealant around the installed unit is recommended to ensure a long-lasting waterproof seal.

• IP67-rated sealing to block water and dust.
• High-density foam pad included for a snug, vibration-resistant fit.
• Recommended to apply butyl sealant after installation for best waterproofing.
• Durable materials and OEM-grade manufacturing standards.

How difficult is installation and what comes in the package?

Installation is straightforward and plug-and-play for compatible trucks—reuse the factory screws and wiring for a clean swap. Avoid overtightening with power tools; hand tools help prevent cracking the housing.

• Pack includes: 1 LED third brake light and 1 high-density foam pad.
• Plug-and-play wiring uses the original connector—no splicing required.
• Use factory screws and hand screwdriver for proper fitment.
• No drilling needed when replacing an OEM cargo-light version.

Who is this for: Truck owners who drive 1994–2000 Chevy or GMC C/K Series pickups with the cargo light-equipped center brake assembly and want a brighter, longer-lasting, weather-resistant LED upgrade. It's ideal for drivers seeking improved rear visibility, reliable cargo illumination, and a simple OEM-style replacement that preserves factory mounting and appearance.
