Peterson 426R Round Red Reflector Lens Grommet Mount Dot

Product Description

The PETERSON 426R is a round replacement reflector lens designed for use on commercial vehicles, trailers, and heavy-duty equipment. Molded in red plastic, the lens measures 4.25 inches in diameter and 2.06 inches in overall thickness, fitting into a standard grommet mount. It meets D.O.T. standards, making it a compliant replacement for federally regulated lighting assemblies. This part is typically installed by truck fleet technicians, trailer repair shops, and commercial vehicle maintenance crews handling lens replacement on marker, clearance, or identification light housings.

The 426R is suited for trailer and commercial truck applications where a grommet-mount round red reflector lens is required. It serves as a direct replacement lens in existing light assemblies rather than a complete lamp unit. Typical install scenarios include roadside repairs, fleet PM cycles, and DOT compliance inspections where cracked or faded lenses must be replaced to maintain legal lighting standards. The plastic construction keeps weight low at 0.25 pounds, which is well-suited for high-vibration vehicle environments.

Compatibility

Designed as a replacement lens for grommet-mount round red reflector light assemblies on commercial trailers and trucks requiring a 4.25-inch diameter DOT-compliant lens.

Installation Notes

Installation is typically performed by a commercial vehicle technician or fleet maintenance professional. Disconnect or power down the vehicle lighting circuit before servicing any lens or light assembly. Grommet-mount lenses are seated by hand pressure into the housing grommet — inspect the grommet for cracking or deformation and replace it if needed before seating the new lens. Verify DOT compliance markings on the installed lens after replacement to confirm the vehicle meets FMCSA lighting requirements.
