- Besides the safety benefits of having clean lights that increase your truck’s visibility, cleaning your lights can keep them cool, leading to overall longer-lasting fleet truck lighting. Dirt on lenses results in a build-up of heat, which could have the opposite effect.
- Regularly lubricate sockets, pigtails, battery terminals and connections with a “non-conductive” anti-corrosion compound. Make sure you don’t use sodium-based greases. This will help encapsulate the system and prevent corrosion by water.
- Inspect the grommets that house the lamps for signs of deterioration from sunlight, ozone and chemicals. New grommets not only restore shock protection but improve security and overall appearance.
- Check for improper ground connections that can cause lamp failure, oftentimes when the trailer is used for a ground. The connection must be clean when lamps are grounded through lamp housing and a fifth wheel ground strap can be utilized for extra protection on the chassis ground system.
- Wiring and harnesses need to be on the underside of top frame members, rather than the bottom where dirt and water can accumulate.
- For older model trucks, you should always avoid cranking the truck when the lights or any accessories are turned on.
- Melted lenses can result from leaving clearance and/or hazard lights on when a truck is parked against a dock.
- Conserve lighting use whenever possible and try to focus on decreasing the overall use of power; voltage surges can be very damaging to lighting and wiring.
