Lighting Technical Tips
Truck-Lite offers the following tips on the lighting and electrical systems. Never use a test probe to pierce wire insulation. Wicking action takes place, which causes moisture to travel along the wire strands and corrode critical components. If you have to probe a wiring harness, make sure the puncture is sealed properly. Test all lamps before discarding them. Up to 20 percent of all lamps that are sent back to TruckLite's warranty department still are in good operating condition. Treat the electrical system as you would the chassis. Lubricate sockets, pigtails, battery terminals and connections with NYK 77 "non-conductive" anti-corrosion compound. The purpose of the sealant is to totally encapsulate and protect against corrosion and water.
Always replace wiring, trailer light cables and harnesses with an equal or heavier gauge of wire than was used on the original specification. If you don't, you may cause unnecessary problems. Look for loose, bare or unsupported wire and fixtures. Harness wiring should be on the underside of top frame members rather than on the bottom where dirt and road splash collect.
