Features and Construction

The roof cab light combines polycarbonate durability with practical electrical specifications for commercial vehicle applications. Its design focuses on compatibility with existing vehicle systems while providing marker lighting functionality.
Material and Build
The light utilises polycarbonate for its lampshade material, providing impact resistance against road debris and weather exposure. A rubber seal at the base creates weather-resistant protection where the unit meets the vehicle roof surface. This construction approach addresses the vibration and moisture challenges common in commercial vehicle operation environments.
Size and Practical Fit
With an 83mm boundary dimension, this light matches standard cab roof mounting cutouts on many commercial vehicles. The diameter specification ensures it can replace existing roof lights without requiring modification to the vehicle body. This practical sizing makes it suitable for repair scenarios where maintaining original mounting positions is important for installation efficiency.
Uses and Placement

This roof cab light serves as marker illumination on commercial vehicles operating in various conditions. Its specifications support both replacement and upgrade applications in professional transport settings.
Event or Professional Use
For commercial fleet operators, this light provides a standardised replacement option for cab roof marker lighting.
