LIGHTING TECNICAL INFORMATION

In this section you will find information on legal requirements for trailer lighting, wiring diagrams for 4, 6 & 7-pole systems, as well as some lighting terminology. Some of the most basic maintenance practices can add years of service to your trailer lighting system. One tip is to always unplug the Boat trailer harness from the tow vehicle before launching and loading. Doing so will prevent thermo shock failure when a hot bulb comes in contact with cold water. Another easy maintenance tip is to coat all exposed metal surfaces with dielectric grease, including trailer harness plugs, bulb sockets and contacts. The grease will help prevent corrosion, which is the leading cause of light failure. Finally, as a safety precaution, always check the trailer lighting for proper operation before heading out on the road.
