Overview

Replace a cracked or water-filled side marker with this 2 x 6 in Reflex LED Marker & Clearance Lamp distributed by FleetPro Parts & Tires. The red lens carries a built-in reflex reflector, so the lamp lights up when the circuit is live and still reflects when it is not โ€” an added margin of safety on a dark shoulder, and one fewer stick-on reflector to buy and glue at that location. A dead marker is a guaranteed DOT inspection write-up and a real hazard on an unlit trailer. We stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, trailer repair shops, and owner-operators nationwide.

Lamp and Reflector in One: The Reflex LED Marker Advantage

This rectangular lamp measures 2 in x 6 in and runs three diodes that give strong, even output while drawing minimal current from the trailer circuit โ€” a real difference when one rail carries a dozen markers on a single fuse. It runs on 12V and arrives with a factory pigtail, so wiring is straightforward on a repair or on a new build. The sealed, weatherproof housing stands up to weather, wash down and vibration, the three things that end an incandescent marker's life early.

At FleetPro Parts & Tires, we know a marker lamp only earns its place if it survives the winter. This Automann lamp is built to Fleet Standard specifications and serves as a direct replacement for highly searched industry numbers including 2150 and M20330R. Buy a spare with it โ€” markers are the cheapest part on the trailer and the one an inspector looks at first.

Key features
  • Lamp and Reflector in One: The built-in reflex lens reflects when the lamp is unlit, so a single part covers the marker point and the side or rear reflector at that location.
  • Three-Diode Even Output: Three diodes give strong, even light while drawing minimal current from the trailer circuit.
  • Sealed Against the Road: The sealed, weatherproof housing shrugs off weather, wash down and vibration that kill filament bulbs.
  • Factory Pigtail Included: The pigtail leads make wiring straightforward on a roadside repair or a new build.
  • One Fewer Part to Buy: The integrated reflector removes the need for a separate stick-on reflector at that position.
