Peterson V428S Round Red Reflector 3.75 in Stud Mount

Product Description

The PETERSON V428S is a round red lens reflector designed for vehicle and trailer lighting applications. Built from durable plastic, this 3.75-inch diameter reflector mounts via a stud-mount system using two mounting holes, providing a secure and low-profile installation. It meets D.O.T. standards and California Proposition 65 requirements, making it suitable for use on commercial vehicles, trailers, and other on-road equipment. Licensed technicians and fleet maintenance professionals install this type of reflector as a replacement or new-installation component on a wide range of vehicle types.

This reflector is well-suited for trailer lighting, truck body work, and other vehicle applications where a D.O.T.-compliant red rear reflector is required. Its round shape and stud-mount design make it a straightforward drop-in replacement for worn or damaged reflectors. The 3.75-inch diameter fits standard cutouts common on utility trailers, flatbeds, and commercial truck bodies. It is also used in new lighting panel builds where reflector placement is required by federal or state vehicle lighting codes.

Installation Notes

Installation is typically performed by fleet maintenance technicians or trailer repair shops. Before replacing a reflector, ensure the vehicle or trailer is parked safely and any associated lighting circuits are de-energized. Use appropriately sized hardware to secure the stud mount through the mounting panel, and verify the reflector sits flush to prevent moisture intrusion. Follow applicable D.O.T. vehicle lighting regulations and any state-specific requirements for reflector placement and visibility angles.
