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 an amber lens, rated SAE P2 PC, and it wires in on 3 lead wires with .180 bullet terminals for the standard 3/4 in grommet-mount positions already in your truck or trailer. A dead marker in a row of live ones is the kind of thing an inspector spots from across the yard. 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 amber 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.

This is the wire-lead version of the lamp, the alternative to the adhesive-back 571.LD361A3 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 36203Y and Peterson Manufacturing M271ABT3.
