Roof & Cab Marker Lights

Roof and cab marker lights are vital safety features commonly found on larger vehicles such as trucks, trailers, RVs, and commercial vehicles. These lights are mounted on the roof or cab of the vehicle and are designed to make the vehicle more visible, especially in low-light or adverse weather conditions. Roof marker lights are typically arranged in a series along the top of the vehicle and are used to indicate the height and width of the vehicle, ensuring other drivers are aware of its presence, especially on highways or in heavy traffic. Cab marker lights, on the other hand, are mounted on the vehicle's cab and serve a similar purpose, providing additional visibility while enhancing the vehicle’s overall aesthetic. These lights are often LED-based for energy efficiency and longevity, offering bright illumination without drawing too much power from the vehicle’s battery.


Both roof and cab marker lights are typically available in a variety of styles, including clear, amber, and red lenses, depending on the specific legal requirements and aesthetic preferences of the vehicle owner. They are built to withstand harsh weather conditions and are often constructed from durable, weather-resistant materials to ensure long-lasting performance. Many modern marker lights feature low-profile designs that don’t interfere with the vehicle's appearance, but still provide the necessary visibility for safety. Whether used for regulatory compliance, visibility enhancement, or purely for style, roof and cab marker lights are crucial for increasing safety and ensuring that larger vehicles are clearly seen on the road, especially at night or in poor visibility conditions.
