The new XPR-S Light bar series provides the ultimate long distance light bar option with 40-90% more distance than the XPR Series. The XPR-S combines powerful 10 watt LEDs with upgraded IRIS reflector technology to outshine and outlast the competition. Prime Drive Technology from Vision X Lighting controls vital functions such as temperature control and dimming on your LED Light Bar. This advanced technology can increase or decrease the intervals at which the LEDs turn on and off in order to lower the bars overall temperature and maximize the lifespan.
