The RIGID Adapt XP has a signature look that is unlike any other motorcycle LED light on the market. The light features a high-strength aluminum heat sink and an impact resistant polycarbonate lens. On the inside it contains cutting-edge technology. The Adapt XP uses two layers of adaptive response. The first layer is RIGID's Active Power Management (APM) system which monitors input voltage to determine the status of the vehicles electrical system. If the voltage is stable, it will continue to utilize all available power to give you the most output possible. If the available voltage begins to drop due to insufficient power, the APM system will gradually reduce the power consumption until the voltage stabilizes. The second layer, the Active View Technology, uses an internal GPS module to determine the bikes speed, allowing the Adapt to properly distribute all available power among three optic zones. Utilizing the three optic zones allows the Active View Technology to create the ideal beam pattern to suit the riders needs. As the vehicles speed changes, power is routed through various optic zones utilizing scene optics for low speed, driving optics for moderate speed and spot optics for high-speed driving. Power is transferred between optic zones allowing for a transition between beam patterns and providing much brighter and more natural looking light and reducing eye fatigue. Also featured is a Magnetic Reed power clip for additional customization. With the clip in place limits the power to a max of 2.7 amps for the single unit, 2.5 amps per light for the pair when all zones are active. Output is 40 watts with the switch in place. With the switch removed the single light consumes up to 6.5 amps, and a pair will consume up to 5.7 amps per light when all zones are active. Single light output with switch removed is 90 watts and output for the pair is 80 watts. Wire harness & switch sold separately
