The Problem
Trailer lights and wiring are exposed to rain, snow, salt, road dirt and grime. The wires and bulbs are subject to chaffing, corrosion and damage. The bulb sockets and ground connections are particularly prone to corrosion.

Trailer lights will
eventually fail |
Trailer lights must be tested often for everyone's safety in traffic and to avoid legal and regulatory citations and fines. Testing trailer lights takes time and time costs money.
Testing trailer lights normally requires a towing vehicle connected to the trailer then walking back and forth from the vehicle to the back of the trailer to verify that all the trailer lights function properly - left signal, right signal, brake lights, tail and clearance lights. A second person could be in the vehicle to operate the lights. But that is double time consuming and very expensive for a business with a fleet of trailers.

Because of the hassle, time and expense, most people don't test their trailer lights in advance. Instead they wait until they are hooked up and do a quick walk around to check the trailer lights then realize they have a problem. But everyone is ready and anxious to go, so off they go traveling or to the job site traveling illegely and not safely. This could result in traffic citations or possibly a much more expensive traffic accident.

What do customers say about Light Check
Light Check has made trailer light checking a lot easer. I check them alone most of the time. It's like having a second person helping.
I do a lot of D.O.T inspections. With Light Check as a tool has made my job more efficient.
Light Check makes it easy to distinguish between vehicle or trailer wiring problems.
It has saved us a lot of time
When I rent out a trailer, sometimes the lights do not work when hooked up to the customers vehicle. I connect Light Check to the trailer and show the customer that the lights on our trailer are working fine. This has helped significantly with customer relations.

The Solution
Light Check is a self-contained, portable device that connects to the wiring connector of the trailer. It includes a 12-volt internal rechargeable battery, electronic diagnostics for light circuit analysis, ground wire, battery charger and instructions.
Simply connect Light Check to your trailer wiring, turn on the power and press Select button for Cycle. Light Check will continue cycling through each of the trailer light circuits in 5 second intervals allowing one person to easily check the signal lights, brake lights, tail and clearance lights without a towing vehicle or second person to assist.
Use the Select button to operate any individual circuit continuously for over current (short circuit) and low current (open circuit). If a problem is detected, LED fault lights will indicate the type and source of the fault.
Save time and money, reduce fines and penalties by testing your trailer lights with LIght Check.
