Peterson 431R Stop Turn Tail Light 4.25in Round 12V

Product Description

The PETERSON 431R is a sealed stop, turn, and tail light designed for 12-volt vehicle electrical systems. Measuring 4.25 inches in length with a round lens profile, this single-bulb light draws 2.1 amps at 25 watts. The red lens and housing are fully sealed against moisture and road debris, making it a reliable choice for trailer, truck, and commercial vehicle lighting applications. Installation uses a standard grommet mount, keeping the fit clean and secure on flat or curved mounting surfaces. This light is typically installed by fleet maintenance technicians, trailer builders, and experienced service professionals.

The 431R is suited for stop, turn, and tail light applications on trailers, utility vehicles, and commercial trucks operating on 12-volt vehicle power. Its sealed construction makes it appropriate for environments where exposure to water, dust, and vibration is a regular concern. The round lens shape and grommet mount style conform to common trailer lighting cutout standards, simplifying direct replacement installations in the field.
