Tresound Amber Roof Cab Marker Light Kit for Chevy/GMC C/K 1988–2000 — 5x T10 5050 SMD LEDs & Bases

Tresound's five-piece amber roof cab marker light kit includes lens covers, mounting bases and five T10 5050-SMD amber LED bulbs designed to replace the original cab/roof running lights on 1988–2000 Chevrolet and GMC C/K pickup trucks.

This complete replacement set gives owners a straightforward route to restore or upgrade the factory roof clearance lights on older Chevy and GMC trucks. The package pairs amber lenses and bases with bright amber T10 5-5050-SMD LEDs, matching the original appearance and DOT/SAE-approved interchange numbers for a correct fit. It’s sold as a matched five-light kit so roof marker spacing and color remain consistent across the cab roof.

How bright and durable are the included LED bulbs?

The kit uses T10 bulbs populated with five 5050 SMD LEDs each, producing a clear amber signal suitable for roof marker and clearance light purposes.

What comes in the package and how easy is installation?

The kit ships with five amber lenses, five pre-molded bases (assembly kits) and five amber T10 LED bulbs—everything needed to replace the five cab marker lights. Installation is typically a bolt-and-connector swap using the factory mounting points; basic hand tools and a short amount of time per light are usually all that’s required.

• 5 amber T10 LED bulbs included; bulbs and bases are matched for each position.
• Designed to bolt into original mounting points with factory wiring compatibility.
• Simple electrical connection—no cutting or splicing if stock harness is present.

Will this maintain legal and factory appearance?

The set was produced to align with the DOT/SAE-approved colors and the OEM part number references listed by manufacturers, so it preserves the original amber color and roof marker layout. Using like-for-like lenses and amber LEDs helps maintain a factory-correct look and expected signaling behavior.

• Amber lens color matches original roof marker appearance.
