Nilight LED Cab Marker Lights for 1988-2002 GMC Chevrolet – Smoked Lens, 5-Piece Amber LED Kit, Direct-Fit

Nilight LED Cab Marker Light with a smoked lens: a plug-and-play amber roof marker kit built to replace OEM cab lights on 1988–2002 GMC and Chevrolet pickups.

These five-piece cab marker lights provide brighter, longer-lasting amber illumination than the original incandescent bulbs, while the smoked polycarbonate lens gives a sleek, low-profile look. Designed to match the factory mounting pattern on C/K series trucks, the set ships with screws, wire nuts, a fuse, switch and extension wire so you can install it as a direct replacement or add them to a truck that didn’t previously have roof markers.

Will these lights fit my 1988–2002 GMC or Chevrolet truck?

Yes — the Nilight kit is engineered for GM full-size pickups from that model range, including C1500, C2500, C3500 and K1500/K2500/K3500 variants. The housings match the common cab marker footprint used on those years, making them a straightforward replacement for original equipment.

• Compatible with GMC and Chevrolet full-size trucks 1988–2002.
• Works as roof cab marker, running light, or clearance light.
• Direct-fit for trucks already equipped with OEM markers; drilling required if no factory holes exist.

How bright and durable are the LEDs compared to originals?

Each light uses five 5050 SMD LEDs that deliver a wider beam, higher intensity and improved heat dissipation versus incandescent bulbs. The LEDs are built for extended service life and consistent amber output, so visibility and reliability are both improved for highway and low-light driving.

• 5050 SMD LEDs for strong amber illumination.
• Improved heat management for longer lifespan.
• Even light spread to meet marker visibility expectations.

Are these cab lights weatherproof and easy to install?

The smoked polycarbonate (PC) lens and ABS base are sealed together and the wiring entry is glued to prevent moisture intrusion, giving robust waterproof protection. Installation is plug-and-play when replacing OEM lights; if your truck lacks roof markers, the kit includes wiring, screws and a fuse, though you will need to drill mounting holes and connect power wires.

• Fully sealed PC lens and ABS housing for moisture resistance.
• Includes wire nuts, screws, fuse, switch and extension wire for retrofit installs.
• Plug-and-play for direct replacements; basic drilling and wiring for new installs.

What comes in the package and what wiring is required?

The kit includes five smoked-lens amber marker lights plus installation hardware and wiring accessories so you have everything needed for a complete roof marker installation. For trucks with existing connectors, simply unplug the old units and plug in the Nilight lights; when adding new markers, cut the plug and attach the black wire to negative and the red wire to positive as instructed.

• 5 smoked-lens amber marker lights with integrated 5050 LEDs.
• 10 screws, wire nuts, one fused power wire, a switch and extension wire.
• Wiring: black to negative, red to positive for direct power connection.

Who this is for: Owners and restorers of 1988–2002 GMC and Chevrolet full-size pickups who want a modern LED upgrade that preserves the truck’s original roof marker appearance while improving brightness, durability and weather resistance. It’s also suited to DIYers adding clearance markers to trucks that never had them, provided they can drill mounting holes and make a simple two-wire connection.
