The Uriah 4-Way Flat Circuit Tester is a compact and essential diagnostic tool for anyone who frequently tows a trailer. Instead of guessing why your trailer lights aren’t working, you can plug this tester directly into your vehicle’s 4-way flat bumper socket to instantly verify that the electrical system is sending power to the right places. The bright LED indicators are designed to show the status of the left turn signal, right turn signal, and tail lights, allowing you to troubleshoot your vehicle’s wiring independently of the trailer. It is a time-saving device that ensures your vehicle is ready for the road before you even hook up your trailer.

To use this tester effectively, have a partner operate the vehicle controls or use a mirror to watch the LEDs while you cycle through the turn signals and headlights. If the tester lights up correctly but your trailer lights still do not work, you know the problem is located within the trailer’s wiring or bulbs rather than the vehicle’s fuse box. It is a good practice to keep this tool in your center console so you can quickly verify your power supply if you experience a light failure while traveling at night.
