Nilight LED Cab Marker Lights for 1988–2002 GMC/Chevy — Smoke Lens 5-Pack, 5050 SMD & Weatherproof

This set of five smoked-lens cab marker lights replaces worn or missing roof markers on classic GMT400 and similar Chevy/GMC pickups. Each lamp uses high-efficiency 5050 SMD LEDs and a sealed ABS/PC housing to improve visibility while resisting water intrusion and road vibration. The kit includes hardware, wire accessories, a fuse, and a switch to make installation straightforward whether you’re swapping into an existing harness or creating a new connection.

How do these LED cab marker lights improve visibility at night?

The 5050 SMD LEDs produce a strong, consistent amber output that is easier to see in low-light and inclement conditions compared with older incandescent bulbs. They have a wider beam angle and greater intensity, helping other drivers notice your truck’s width and position sooner.

• Five high-output 5050 SMD LEDs per lamp for brighter amber light
• Wider lighting angle to cover more lateral area
• Consistent illumination with no filament burnout

Are these lights durable and weather-resistant?

Yes — the lights combine a polycarbonate (PC) smoked lens with an ABS base and added sealing at the wiring entry points to keep moisture and dust out. The assembly is reinforced with adhesive at critical joints to improve long-term waterproofing and reduce the risk of corrosion.

• PC lens plus ABS housing for impact and UV resistance
• Sealed wiring and glue at the cable entry for full protection
• Built to withstand road vibration, rain, and spray

How simple is installation on 1988–2002 GMC and Chevy trucks?

Installation is plug-and-play when you have an existing factory cab marker harness; the lights are designed to directly replace OEM units. If your truck lacks roof markers, you can drill mounting holes, use the supplied wire harness, or splice into power: black to negative, red to positive.

• Direct replacement for OEM-installed cab markers on compatible trucks
• Includes screws, wire nuts, fuse, switch and extension wire for new installs
• Simple wiring: black = ground, red = power (cut-and-splice option available)

What’s included and will I need extra parts?

The package contains five smoked amber marker lights plus the common consumables needed for fitting and basic wiring. For custom installations or vehicles without factory holes, you may need a drill, silicone sealant for final waterproofing, and basic hand tools.

• 5 smoked-lens amber marker lights, 10 screws, wire nuts
• 1 power wire with fuse, 1 switch and extension wire included
• Optional tools: drill, sealant, basic hand tools for custom installs

It’s also a practical upgrade for restorers and truck enthusiasts seeking improved visibility and a subtle smoked aesthetic without complex wiring work.
