Better Visibility for the Road: Dual-Bulb Red Clearance and Marker Light

When you want to make sure your trailer is easy to see day or night, this 4-1/8" x 2" Peterson oblong light gets the job done. It uses two 194 incandescent bulbs under a red snap-on acrylic lens to shine bright and clear. Rated for 12V systems and drawing only 0.25 amps, it works as both a clearance and side marker light when properly mounted. The PC rating means it spreads light across a full 180 degrees, giving clear visibility from the front and sides for improved safety on the road.

Built for Long Service: Premium Incandescent Bulbs

This light doesn’t cut corners on bulb quality. The pair of premium 194/193 bulbs are designed for up to 15,000 hours of illumination—plenty of time before you’ll need replacements. That long life means less time spent dealing with burned-out bulbs and more time focusing on towing safely and confidently.

Simple Mounting Where You Need It: Surface-Mount Design

Installing this light is easy thanks to its surface-mount design. It attaches flat against the trailer surface using two mounting holes spaced 3" apart (center to center). Only a small wiring hole is needed since the light grounds through its single-wire connection and mounting hardware. Whether you’re replacing old lights or adding new ones, this design keeps installation straightforward and clean.

Reliable Construction for Everyday Use: Snap-On Acrylic Lens

Durability matters when your gear faces the elements. The snap-on red acrylic lens protects the bulbs while letting the light shine bright without distortion. It’s DOT compliant and built to handle regular road use, giving you a dependable light that holds up trip after trip.

Direct OEM Replacement Confidence: Cross-Reference Compatibility

This Peterson light lines up with multiple well-known part numbers—Truck-Lite #1259, Grote #45262, Optronics #MC66RB, and Primatronics #PT2601R—so you can count on it as an exact replacement without having to drill new holes or rewire your setup. It’s a straightforward swap that restores proper lighting fast.
