This is one amber polycarbonate outer lens for Stage Series LED light bars. It can be used to change the performance and output pattern of your Stage Series Light Bar. The installation process is straightforward, but must be completed at your own risk. It requires removing the frame using a 2mm hex driver bit (not included), removing the original lens, removing the O-ring from the lens, placing the O-ring onto the new lens, placing it in position, and securing the frame back into place. We recommend finding a clean area, wearing protective gloves, and taking your time. Do not overtighten screws. NOTE: If you choose to change the lens yourself, any warranty claim for moisture or condensation will require the light bar to be returned to our facility for repair, rather than direct replacement.
