Shedding Light on Effective Diagnostic Testing and Repair

Industry News | 06.27.23 | Carlos Romious

Proper lighting maintenance is crucial in truck fleet management. Not only does neglecting upkeep lead to downtime, lost revenue, and road violations but research by the American Trucking Association (ATA) shows inadequate lighting maintenance also contributes to accidents with increased liability attributed to both the driver and fleet owner. For these reasons the importance of diagnostic testing and repair for optimal lighting performance cannot be understated.   

Importance of Lighting Diagnostic Testing 

In the world of truck fleet maintenance, routine inspections only scratch the surface when it comes to ensuring the integrity of lighting systems. This is where diagnostic testing plays a pivotal role. Proactively assessing each lighting component can help you identify underlying issues like burned-out bulbs, malfunctioning connectors, or wiring issues before they become major problems. 

Ensuring the proper functioning of a truck’s lighting system is not just about meeting regulations; it’s about guaranteeing the safety of drivers, other road users, and the cargo being transported. Faulty lighting can lead to accidents, violations, and unnecessary downtime. Regular lighting diagnostic testing is crucial in identifying issues before they escalate, allowing for timely repairs and uninterrupted operations. 

Tools and Techniques Used for Lighting Diagnostic Testing 

As fleet maintenance personnel, you need the right tools and techniques to diagnose lighting issues effectively. Essential tools include a multimeter, circuit tester, and trailer light tester. These tools enable accurate measurements, voltage checks, and identification of faulty components. 

The diagnostic testing process involves a step-by-step approach. Start by visually inspecting the lighting system, looking for loose connections, damaged wires, or signs of corrosion. Next, use the tools mentioned earlier to test each component individually, including the headlights, taillights, turn signals, and brake lights. Document any abnormalities and address them promptly. Flickering lights, faulty wiring connections, and burned-out bulbs are just some of the common issues that you may find during your diagnostic testing. 

Peterson provides a Lighting Troubleshooting and Repair Guide to help with the diagnostic process which also includes the latest copy of the Technology & Maintenance Council (TMC) guidelines. Following these industry standards ensures consistent and reliable testing, accurate problem identification, and efficient repairs.

Once diagnostic testing has uncovered malfunctions, addressing them promptly and effectively is essential. To address these issues, follow proper repair procedures. TMC guidelines provide a reliable framework for addressing lighting system problems. Adhering to these guidelines ensures your drivers’ safety, reduces the risk of accidents, and minimizes potential road violations. 

How to Prevent Corrosion for Long-lasting Lighting 

Corrosion remains a primary source of faulty lighting, leading to intermittent malfunctions and compromised safety. Preventing corrosion is crucial for maintaining reliable lighting. 

One effective solution is the adoption of weatherproof over-molded connections. These connections act as a protective barrier, preventing moisture and environmental factors from infiltrating your wiring system. Adopting weatherproof over-molded connections can significantly reduce corrosion-related issues and enhance the longevity of your lighting system. Here are the benefits of utilizing over-molded connections: 

  • Enhanced durability: Weatherproof connections are specifically designed to withstand ruthless weather conditions, including rain, snow, and extreme temperatures, and extend the lighting system’s lifespan. 
  • Reduced maintenance requirements: Weatherproof over-molded connections provide an effective moisture-resistant barrier, minimizing the risk of corrosion. With reduced exposure to moisture and environmental elements, your lighting system requires less maintenance, saving time and resources. 
  • Optimal electrical conductivity: Weatherproofed over-molded connections ensure consistent electrical conductivity, minimizing voltage drops and improving lighting system performance. You can enhance visibility and safety on the road by maintaining reliable connections.
