Need a bright, dependable marker that doesn’t take up much space? This Peterson clearance and side marker light measures just 2-1/2" long by 1-1/4" tall and uses an amber lens over a premium incandescent bulb. It shines clearly to mark the trailer’s edges and corners, helping other drivers spot you in low light or at night. The bulb is rated for up to 15,000 hours, so it keeps working season after season without constant replacements.
Moisture can be tough on trailer lights, but this one is designed to handle it. The housing and lens are completely sealed together, making the unit waterproof and submersible. That sealed design protects the bulb and internal wiring from water intrusion and corrosion, so it’s ready for wet roads or even full submersion during boat launches.
This light isn’t limited to straight-ahead illumination. It’s PC-rated to throw light 90 degrees to either side of center, giving a total of 180 degrees of coverage. When mounted correctly, it can work as both a clearance light and a side marker light, increasing visibility from the front, side, or rear angles—exactly what you want for safety on the road.
Getting it installed is simple. The light surface-mounts flat against your trailer using a bracket (150-09, sold separately) and connects through standard male terminals that accept a 2-wire female plug (153-49, sold separately). The surface mount keeps wiring protected and neat while making replacement or maintenance quick and easy.
You can count on this light meeting the right standards. It’s DOT compliant and built to handle everyday use while staying securely in place. The compact rectangle shape and durable construction make it a reliable pick for anyone looking to replace or upgrade their trailer’s lighting system with something proven to last.
