Peterson 426-18 Black Round Grommet Reflector 4.25 in

Product Description

The PETERSON 426-18 is a round replacement reflector lens designed for vehicle lighting and marker light assemblies. Made from rubber, this black lens measures 4.25 inches in diameter and mounts via a grommet-style connection for a secure, vibration-resistant fit. The rubber construction provides flexibility during installation and resistance to weather exposure. This reflector serves as a direct replacement lens component within lighting housings where the original lens has cracked, faded, or gone missing. Fleet maintenance shops, trailer repair technicians, and commercial vehicle service pros will recognize this as a standard consumable in marker and clearance light upkeep.

This replacement lens is suited for use on trailers, trucks, and commercial vehicles where round grommet-mount reflector assemblies are standard. The 4.25-inch diameter fits housings designed for that size opening. The black color and round shape are common in side marker, rear reflector, and clearance light applications. Installation requires no special tools beyond basic hand tools to seat the grommet. Technicians working on DOT-regulated vehicles should verify the replacement meets applicable lighting standards for the jurisdiction.

Installation Notes

Seat the grommet evenly around the housing opening to ensure a weathertight seal. Confirm the replacement lens is properly seated before restoring power to the lighting system.
