Overview

Put the front corner of the truck back on the road-legal side of a DOT inspection with this 4in amber front, park and turn LED lamp distributed by FleetPro Parts & Tires. It carries 24 high-output diodes behind an amber lens and includes a built-in reflector, so the corner stays visible whether the lamp is lit or the truck is parked dark on a shoulder. A dim or dead front lamp is an inspection failure and, worse, the reason a car turning across your bow never saw the corner of the tractor. 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.

Seen From The Corner: The 24-Diode Amber LED Advantage

Twenty-four diodes is a high count for a 4in lamp, and the payoff is a bright, even face rather than a handful of hot spots - plus the instant-on response an LED gives a turn signal, where an incandescent bulb has to warm up before the car beside you registers the flash. It runs on 12 Volt and meets FMVSS 108 with SAE code IP, the front park and turn classification, so it satisfies the inspector as well as the driver.

Installation is a grommet mount, a direct drop into the standard grommets and flanges already on the truck or trailer, and the whole lamp weighs 0.45 lbs. If your fleet is still running incandescent in this position, Automann's matching bulb-type lamp is 571.LG40A - but moving the corner to LED is how you stop pulling the same lamp apart every winter. This unit is a direct replacement for highly searched industry numbers including Grand General 78270, UBLights MTLED4000-24A and MTLED400024A, and Uni-Bond LED4000-24A and LED400024A.

Key features
  • 24-Diode Output: A high diode count for a 4in lamp gives a bright, even lit face instead of a few hot spots on the lens.
  • Built-In Reflector: Keeps the front corner visible when the lamp is unlit and the truck is parked on a dark shoulder.
  • Instant-On For Turn Signals: LEDs light the moment the switch closes, with none of the warm-up delay of an incandescent bulb.
  • FMVSS 108 With SAE Code IP: Carries the front park and turn classification an inspector looks for.
  • Drops Into Standard Grommets: Grommet mount on 12 Volt, so it replaces the existing corner lamp without modifying the panel.
