Light Check Trailer Light Test

Inventor Paul Wolf and Wolf Technologies, LLC of Mandan, ND created a self-contained, portable device that connects to the wiring connector of a trailer. It includes a 12-volt internal rechargeable battery, electronic diagnostics for light circuit analysis, and ground wire and battery charger.

Due to the time, hassle, and expense, many people do not test their trailer lights in advance. Instead, they wait until they are hooked up and ready to go, before realizing they have a problem. Trailer lights must be regularly tested for safety, legal, and regulatory compliance. Ignoring this responsibility can lead to traffic citations or a much more expensive and hazardous traffic accident. Testing trailer lights normally requires a towing vehicle connected to the trailer, followed by one walking back and forth from the vehicle to the back of the trailer to verify that all the trailer lights are functioning properly. A second person is sometimes needed in the vehicle to operate the lights. This process is truly inconvenient. Inventor Wolf and Wolf Technologies, LLC have created an improved means of testing trailer lights.

This clever new invention cycles through all trailer light circuits in five second intervals. LED fault lights indicate the type and source of the fault. The device saves time and money. It prevents traffic citations and accidents. No towing vehicle or second person is needed to perform the test. The use of the Light Check Trailer Light Test simplifies the process of testing trailer lights for individuals and businesses with a fleet of trailers, in a manner which is quick, easy, and effective.
