Nilight LED Third Brake Light for Chevy GMC C/K Series 1994–2000 — 26-LED Brake & Cargo, IP67 Weatherproof

Nilight's LED third brake light is a plug-and-play replacement for Chevy and GMC C/K Series trucks (1994–2000) that restores a brighter, longer-lasting center brake and cargo light. This high-output LED assembly is designed to replace factory halogen units on C1500/C2500/C3500 and K1500/K2500/K3500 trucks from 1994 through 2000 (only fits trucks with the cargo light function). Built by OEM-approved manufacturers with quality OE-grade materials, the unit uses 26 integrated LEDs for faster illumination and improved visibility compared with the original halogen lamp. IP67 sealing and a supplied high-density foam pad help protect the fixture from moisture, while the plug-and-play harness and factory screw locations make installation straightforward.

Will this light fit my truck model and year?

Yes — the Nilight third brake light is designed specifically for Chevy and GMC C/K Series trucks from 1994 to 2000 that include the cargo light function. It replaces OEM part numbers 16521970 and 15030176 and mounts using the factory hardware and locations for a direct fit.

• Compatible models: C1500, C2500, C3500, K1500, K2500, K3500
• Model years supported: 1994–2000
• Replaces OEM: 16521970, 15030176
• Requirement: vehicle must have original cargo light function

How does the Nilight LED compare to the original halogen light?

The LED assembly uses 26 built-in LEDs (14 brake, 12 cargo) that produce a brighter, quicker response than stock halogen bulbs. That faster on-off response and higher luminous efficiency improve night visibility and help communicate braking to drivers behind you.

• 26 total LEDs: 14 brake, 12 cargo light
• Faster illumination than halogen for quicker signaling
• Higher brightness and longer service life than OEM halogen

Is the light weatherproof and durable for outdoor use?

The housing features an IP67-grade seal and ships with a high-density foam mounting pad to block water intrusion. For best long-term protection, apply butyl sealant around the fixture after installation to ensure a watertight barrier against rain, snow, and road spray.

• IP67 waterproof rating for heavy rain and splash resistance
• High-density foam pad included for secure, sealed mounting
• Manufacturer recommendation: use butyl sealant after install

How easy is installation — do I need special tools or wiring?

Installation is plug-and-play and uses existing factory screw holes, so no drilling or wiring modifications are required when your truck has the cargo light function. Use the vehicle’s original screws and a hand screwdriver to avoid overtightening and cracking the housing; avoid heavy electronic screwdrivers.

• No drilling or cutting required for direct-fit installations
• Use factory screws (included foam pad only) and hand screwdriver
• Comes with one LED third brake light and one foam pad

Who is this for? This Nilight LED third brake light is intended for owners of Chevy or GMC full-size C/K Series trucks (1994–2000) who want a reliable, brighter replacement for their factory halogen third brake/cargo light. It’s ideal if you prefer an easy, bolt-in upgrade with improved visibility, durable weather sealing, and OE-quality construction without modifying wiring or drilling into the cab.
