Overview

Cover two jobs with one lamp using this 3/4in Round Dual Function LED Marker Light distributed by FleetPro Parts & Tires. It is a sealed 3-diode marker and clearance light with a red lens, rated SAE P2 PC, wiring in on 3 lead wires with .180 bullet terminals for the standard 3/4 in grommet-mount positions already on your truck or trailer. One dark red marker at the rear is all it takes to turn a clean pre-trip into a violation. Manufactured by Automann to Fleet Standard specifications, this lamp is stocked heavily right here in our Hanover Park, Illinois warehouse for lightning-fast shipping to fleets, trailer repair shops, and owner-operators nationwide.

Two Functions, One 3/4in Hole: The Dual Function LED Marker Advantage

This lamp is dual function, rated SAE P2 PC. Three LEDs sit behind the red lens in a sealed housing, so there is no socket to corrode, no bulb to replace and no filament to break when the trailer takes a hard dock hit. Instant-on response is the safety difference that matters when the truck behind you is closing at highway speed.

This is the wire-lead version of the lamp, the alternative to the adhesive-back 571.LD361R3 for anyone who would rather hardwire a marker than trust tape on a dirty panel. The 3 lead wires terminate in .180 bullets, so it plugs into the connectors already in the harness. At FleetPro Parts & Tires we know compliance is king. This Automann lamp is a direct replacement for highly searched industry numbers including Trucklite 36203R, Peterson Manufacturing M271RBT3 and Optronics MCL10RKDTPGS.
