This 4-1/4" round Peterson tail light handles stop, turn, and tail functions in one sealed unit. The red lens sits over an incandescent bulb rated for up to 15,000 hours of use, giving you dependable light for the long haul. It’s built for 12V DC systems and keeps your trailer visible and compliant with DOT standards, so you stay safe and legal wherever you go.
Road spray and rain don’t bother this light. The tongue-and-groove lens seal locks out water and dust to protect the internals, while the durable polycarbonate housing keeps everything inside secure. Whether you’re hauling down wet highways or backing into a boat ramp, its weatherproof design helps prevent corrosion and premature failure.
Designed for recessed mounting, this light installs with the included grommet that holds it firmly in place by compression—even in 1/8" thick diamond plate. It needs a 4-1/2" cutout and sits flush for a clean finish that won’t snag or get in the way. The result is a solid fit that looks professional and stays put through vibration and rough roads.
Wiring is simple thanks to the included 3-wire plug. White is ground, black powers the tail light, and red runs the turn signal. Once connected, you’re set with a stop, turn, and tail circuit that’s quick to hook up and easy to troubleshoot later if needed—no extra adapters required.
Inside, the wedge-base socket keeps the bulb firmly seated to resist vibration and extend life. That small detail helps prevent flickering or early burnout, so you get steady illumination mile after mile without needing frequent replacements.
