Peterson 426KR Stop Turn Tail Light 12V Red Grommet

Product Description

The PETERSON 426KR is a sealed, round stop/turn/tail light designed for 12-volt vehicle electrical systems. Measuring 4.25 inches in length with a round red lens, this single-bulb light draws 2.1 amps at 25 watts under stop and turn operation and 0.59 amps in tail mode. It mounts via a standard grommet, making installation straightforward in truck, trailer, and utility vehicle applications. The sealed construction protects the bulb and socket from moisture and road contamination, extending service life in demanding field conditions. Licensed electricians and trailer technicians working to FMCSA lighting compliance standards will find this a direct-fit, code-ready component.

This light is suited for use on trailers, trucks, and commercial transport vehicles requiring a combined stop, turn, and tail function in a single compact housing. The grommet mount style fits standard cutout openings commonly found on aluminum and steel trailer sidewalls and fender panels. The kit includes the 426R light, a 431-491 straight plug, and a grommet, so installers have the hardware needed to complete the mounting without sourcing additional components. Typical applications include flatbed trailers, enclosed cargo trailers, and light-duty utility vehicles operating on 12-volt DC vehicle power.

Installation Notes

Installation is typically performed by a trailer technician or licensed electrician familiar with FMCSA lighting requirements and applicable vehicle wiring standards. Disconnect vehicle or trailer power before removing the existing light or making any wiring connections. Seat the grommet fully in the panel cutout before securing the light body to prevent vibration damage and moisture ingress. Verify polarity and circuit continuity with a test light or multimeter before returning the vehicle to service.
