Nilight LED Cab Marker Lights — Smoked Lens for 1988–2002 GMC/Chevy Trucks, 5050 SMD Amber Output

Nilight smoked-lens LED cab marker lights replace factory roof markers on 1988–2002 GMC and Chevrolet pickups, delivering brighter amber visibility with sealed, plug-and-play convenience.

These Nilight cab marker lights are designed as a direct-fit upgrade for C1500, C2500, C3500 and K-series trucks from 1988 through 2002. They use high-output 5050 SMD LEDs behind a smoked polycarbonate lens and a durable ABS housing to improve light intensity and weather resistance without altering your truck's exterior styling. The kit ships complete with wiring, hardware, a fuse, and an inline switch for easy installation whether you're swapping into an existing factory footprint or drilling and wiring a roof that currently has no markers.

How do these lights compare to the original factory markers?

The Nilight lights use five 5050 SMD LEDs per unit, offering a wider beam and higher lumen output than most older incandescent markers. That means crisper, more noticeable amber illumination for better daytime and nighttime presence. The smoked lens gives a low-profile, modern look while still passing a bright amber signal when powered.

• Five high-quality 5050 SMD LEDs for increased brightness
• Broader light spread compared with legacy bulbs
• Smoked polycarbonate lens for contemporary appearance
• Amber output retained despite smoked styling

Are the lights weatherproof and built to last?

Yes. The lens and ABS base are tightly bonded and the wiring entry point is sealed with adhesive to minimize moisture intrusion. The materials chosen resist UV exposure and road debris, while the LED design reduces heat buildup, extending service life versus incandescent fixtures.

• Integrated PC lens and ABS shell for a tight seal
• Additional glue at the wiring junction for improved waterproofing
• LEDs run cooler and have longer rated life than bulbs
• Durable construction suited for daily driving and off-road conditions

How difficult is installation on trucks with or without existing roof markers?

Installation is straightforward for trucks that already have factory cab marker openings — the lights are plug-and-play replacements. For roofs without markers you will need to drill mounting holes and connect the wiring: black to negative, red to positive; the kit includes wire nuts, a fuse, switch and extension wire to simplify that process.

• Direct replacement when matching OEM mounting holes are present
• Includes screws, wiring, inline fuse and switch for new installs
• Cut-and-splice wiring instructions for custom installations
• Basic hand tools and a drill are the only additional requirements

Will these fit my specific truck model years?

These marker lights are specified for GMC and Chevrolet C1500/C2500/C3500 and K1500/K2500/K3500 trucks manufactured from 1988 through 2002. They are intended to replace the stock roof marker lights used on those models and are offered as a direct-fit option in most cases.

• Compatible with 1988–2002 GMC and Chevy C/K series pickups
• Sold as a 5-piece smoked lens amber marker light set
• Includes mounting screws and wiring accessories for full installation
• Verify your truck’s roof marker footprint before purchase

Who is this for? These Nilight smoked-lens LED cab marker lights suit owners of late-1980s through early-2000s Chevy and GMC trucks who want a modern, brighter amber marker without dramatically changing their vehicle’s look. They’re a good choice for daily drivers, restoration projects, and enthusiasts seeking improved visibility and a low-profile aesthetic. If you need a straightforward factory-style replacement or a clean upgrade with included wiring and hardware, this kit provides the components and durability expected for roof-mounted marker lights.
