Trailer Clearance / Marker Lighting

One LED Fender Mount Clearance Marker Light with Pigtail & Bracket - Red / Amber Trailer Light

This listing is for one compact LED fender mount clearance marker light with pigtail and bracket. It is a smart fit for trailer applications needing a single replacement light with red and amber visibility in a slim, service-ready footprint.

Part Number: MCL-67ARB 1 Light Included 3-7/8" x 1-1/4" x 7/8"

Overview

If you only need one replacement instead of a pair, this single LED fender mount clearance marker light keeps the repair simple. The light uses a one-wire connection with ground through the mounting screw, measures 3-7/8" x 1-1/4" x 7/8", and contains 6 LEDs total with 3 red and 3 orange LEDs.

R&P Service Insight

Single-light listings are especially useful when only one side is damaged, one light failed, or you want to replace a problem unit without buying a full pair. This style stays compact while combining red and amber lighting in one assembly.

Ground Path: Reliable operation depends on a clean mounting point because the light grounds through the mounting screw.
Compact Profile: The slim size works well on trailer fenders and other tight mounting areas.
Single Replacement Value: A one-light option helps avoid overbuying when only one assembly needs service.

R&P Knowledge Hub

Compatibility: Designed as a compact fender mount clearance / marker light style for trailer applications using red and amber directional visibility.

Vehicle / System Fit: Best suited for trailer lighting setups using a slim fender-mounted side marker / clearance light.

Installation Notes: Verify overall dimensions, mounting footprint, wire routing, and that the mounting surface can provide a clean screw-ground connection before ordering.

Performance Insight: This light uses 6 LEDs total — 3 red and 3 orange — to deliver combined marker / clearance functionality in a compact service replacement format.

R&P Repair Insight

The biggest buyer-side failure point on this style is usually grounding, not the lens format. Since this is a one-wire light that grounds through the mounting screw, paint, corrosion, or debris at the install point can cause intermittent or failed operation. Buyers should also confirm the exact size before ordering because compact fender lights can look similar while mounting differently.

Check Size: Match the replacement area to the listed 3-7/8" x 1-1/4" x 7/8" dimensions.
Check Wiring Style: This is a one-wire light and not a separate-ground two-wire design.
Check Mounting Surface: Clean metal-to-metal contact is important for proper screw-ground performance.
