The Fixed Top Mount allows for a full 450˚ of rotation. This means that light coverage can be a full circle, plus another quarter turn which ensures no blind spot. The 570 base has a built-in stop to prevent the internal wiring from binding. A built-in friction mechanism ensures the light will not rotate when the vehicle is in motion. The pedestal has a round mounting base attached to a side mount bracket.
Fire Research Optimum model OPA580-H15 side mount fixed pedestal light shall be installed. The pedestal shall allow the lamphead to rotate 450˚ and have a self adjusting friction brake to prevent arbitrary rotation. The pedestal shall have a round mounting base attached to a 5" side mount bracket. Wiring shall extend from the bracket bottom.
