The ST Evolution auxiliary light series is the perfect choice when it comes to compact auxiliary light bars with both a long and wide light pattern. The ST series offers durable light bars that are based on advanced technology and have a sophisticated heat treatment system. Thanks to the color temperature of 5000 Kelvin, the ST series maximizes contrasts while reducing eye strain when driving at night. The ST Evolution's stylish and low profile is not only easy to install, but also resists dirt, snow and ice better than many other light bars.
