What Are Camper Running Lights?

Camper running lights, also known as marker lights, are an essential component of any recreational vehicle (RV) or camper's lighting system. These lights are designed to improve visibility and ensure safety, particularly during low-light conditions such as dusk, dawn, or nighttime driving. Unlike headlights, which are used to illuminate the road ahead, running lights serve as a visual indicator to other drivers, making your camper more visible from a distance.

Running lights are typically located on the front, sides, and rear of the camper. They are usually amber or white in color and are positioned to outline the vehicle's profile. By illuminating the camper's dimensions, running lights help other drivers gauge the size and position of your vehicle, reducing the risk of accidents. This is especially important for larger vehicles like campers, which may be more challenging to maneuver on the road.

In addition to enhancing safety, running lights also play a role in compliance with traffic regulations. Many states and countries require vehicles, including campers, to have functioning running lights when driving at night or in poor weather conditions. Failing to adhere to these regulations can result in fines or penalties. Therefore, ensuring that your camper running lights are in good working order is not only a matter of safety but also a legal obligation.

Why Do Running Lights Stay On While Parked?

One of the most common issues camper owners face is their running lights staying on even when the vehicle is parked. This can be both frustrating and concerning, as it may lead to a drained battery and leave you stranded. There are several reasons why this might occur, ranging from simple wiring issues to more complex electrical system faults.

One possible cause is a malfunctioning switch or relay. The switch that controls your running lights may be stuck in the "on" position, causing the lights to remain illuminated even when the vehicle is turned off. Similarly, a faulty relay can send continuous power to the lights, preventing them from turning off when they should. These issues can often be traced back to wear and tear or poor-quality components.

Another potential cause is a wiring problem. Over time, the wiring in your camper's electrical system can become damaged or corroded, leading to unintended electrical connections. For instance, a short circuit in the wiring harness can cause the running lights to stay on, even when the ignition is off. This is why it’s important to regularly inspect your camper's wiring and address any signs of damage or corrosion promptly.
