CURT 59236 Weather-Resistant Trailer Tail Light Converter Kit – 4-Pin Harness (Blue)

Overview

The CURT 59236 Weather-Resistant Multi-Function Splice-in Trailer Tail Light Converter Kit is built to endure rain, road spray, and road salt. Its rugged, potted enclosure seals the internal electronics in a watertight shell, protecting connections for years of use—even when mounted on the exterior of your vehicle. A solid compound fills the chamber to cushion components against bumps and vibrations.

Smart design for a wide range of trailer wiring

Compatible with two-wire, three-wire, or PWM systems, the converter reconfigures signals to a simple two-wire output via a standard 4-way flat connector. A microprocessor monitors current flow and reacts quickly to overloads, while filtering out noisy input signals to safeguard your wiring. The SMT circuitry reduces resistance and heat, contributing to longer life.

Durability and reliability you can feel

• The potted enclosure and solid compound deliver enhanced water and vibration resistance.
• SMT circuitry lowers resistance and heat generation for higher reliability.
• Seven-volt low-voltage operation adds a safety margin in varying conditions.
• The dust cover protects the 4-way connector when exposed to dust or spray.

What you get and how to install

Color-coded wires pair with an easy-to-read wiring guide, making installation straightforward. The package includes a powered converter wiring kit #55152 and four snap locks for quick, secure splicing, plus a dust cover to shield the 4-way connector when not in use.

Real-world use cases

Ideal for upgrading older trailers—utility, boat, or camper trailers—where a compact, weather-ready interface helps keep lights in sync with braking and turning signals. The rugged build inspires confidence during weekend trips and exposed roadside stops.
