Overview

Bring the roof line back to new with this LED Cab Marker Light for Peterbilt and Kenworth, distributed by FleetPro Parts & Tires. Cab marker lights sit in the worst spot on the truck โ€” full sun, full weather, full wind โ€” so the lens fades, the gasket hardens and water eventually finds the roof. A yellowed or dark cab light is an inspection item and the first thing anyone sees pulling up behind you at the fuel island. We stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, diesel repair shops, and owner-operators nationwide.

Roof Line Restored: The 31-Diode Chrome Cab Marker Advantage

This is a complete assembly, not just a lens: 31 diodes behind an amber lens in a chrome housing, supplied with a foam gasket that seals the light to the cab roof and takes up the small irregularities an old, compressed gasket leaves behind. The body measures 10.75 in long with 9 in center-to-center mounting holes, and it runs on 12V. Thirty-one diodes give a bright, even bar of light with no filament inside to fail from the constant vibration a cab roof sees, and LED current draw is a fraction of what an incandescent marker pulls.

At FleetPro Parts & Tires, we know a cab light job is worth doing once. Built by Automann to Fleet Standard specifications, this lamp is a direct replacement for the highly searched industry number 39996. Replace the full roof line at the same time so the lenses match.
