A must have item for any RV'ers tool box! Works well in determining your trailer lighting needs, especially if you are having trailer lighting issues that require some easy troubleshooting. Anyone can use this.

The abbreviations could be more foolproof, but for the money it works just fine. Helped me verify my recent wiring repair

Like the product but can't understand why the light displays is attached so that when it is plugged in has the display underneath. You have to get on your knees to see what is displaying. At least you do for my Ford F150. May be different for other Vehicles.
Was missing set screw
