Its fully sealed internal construction provides reliable dustproof and waterproof performance, enabling stable lighting performance under harsh working conditions including heavy rain, snow and bumpy muddy roads.

Designed with a fixed 60mm screw mounting distance, the lamp supports simple surface mounting without complicated vehicle modification. Its compact trapezoidal shape with overall size of 90×62×50mm fits perfectly to matching cab installation positions, serving as a premium aftermarket replacement and upgrade lighting part for various commercial truck models.
