Have you ever been just about to leave to a job site or go on a vacation, only to hook up to your trailer to find that your lights are not working and have no idea what the problem is? Never will this happen again with this tester! This checks to see of the 12V power is running from your tow vehicle is reaching your trailer plug or if there is something wrong with the wiring.
Most of Today's trucks have dedicated fuses for the trailer wire circuits, so until now, you really had no way to check and test fuses and trailer power, to confirm the truck is working as it should!
Easy to use
- Plug your tester into the tow vehicle's towing plug
- Operate vehicle's turn signals, lights and brakes
- When the power is present, the tester's green LED light will glow
