The Optronics MC65 / MC67 Series Red Marker and Clearance Light is a durable, industry-standard trailer light designed for reliable visibility and long service life. This compact thinline marker lamp is commonly used on cargo trailers, utility trailers, RVs, and commercial trucks, and serves as a direct replacement for Bargman #38 marker lights.

Featuring a sealed polycarbonate housing and lens, the MC65 series light is built to withstand road vibration, moisture, and harsh weather conditions. Its sonically sealed waterproof construction prevents water intrusion, making it ideal for trailers exposed to rain, road spray, and occasional submersion.

With a slim 3-15/16" x 1-1/4" rectangular design, this marker light mounts on standard 3-inch centers, allowing easy replacement of many older trailer clearance lights without modifying the mounting holes.

The MC67 version includes the same MC65 light installed in a self-grounding mounting bracket with wiring pigtail, providing a complete kit for simple installation on trailers and truck bodies.

Designed for 12-volt trailer electrical systems, the light uses two replaceable incandescent bulbs and produces the wide illumination pattern required for DOT-compliant marker and clearance lights.
