Test your trailer lights easily
and quickly before you hook up

Trailer lights will eventually fail

Rain, salt, mud, snow, water, bumps in the road cause corrosion, chaffing, broken bulbs and wires. Trailer lights must be tested often for legal and regulatory compliance as well as everyone's safety in traffic.

Light Check is a self-contained, portable device with its own 12-volt battery for testing trailer lights. Simply connect Light Check to the wiring connector of a trailer to easily test trailer lights without a towing vehicle or second person to assist. When there is a problem, Internal electronic diagnostics will tell you type and source of the problem. Testing your trailer lights will no longer be time consuming or a hassle.
