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.

Interpretations
A United States The front sidemarker must be mounted so that it is visible 45 degrees left and right without obstruction from the trailer or tow vehicle to comply with NHTSA's interpretation of "as far forward as practical."
B Canada The front sidemarker must be mounted from 39" to 60" from the front of the trailer and be visible from 45 degrees left and right without obstruction from the trailer and tow vehicle to comply with Transport Canada's interpretation of "as far forward as practical."

SPECIAL TIPS
Avoid routing wires over sharp edges or pinching them. All splices should be sealed with flexible-waterproof calking for extra protection.
