The ARB Auxilliary Light includes a unique ARB BASE Rack bracket, over molded DT connector suitable for BASE Rack channelling, an additional DT connector for custom wiring, and a scene lighting beam to reduce hot spots in beam output and reduce glare for reverse cameras.The unique ARB BASE Rack bracket provides the ability for installation to any part of the BASE Rack's dovetail system. It can be wired to provide additional aux lighting around the vehicle for camping, working, or reverse lighting. Being compact at 2.8 x 2.21 inches, it allows for mounting in close-fitting areas and along the edge of the BASE Rack to minimize damage on tight roads and close parking. Its compact size further provides a sleek look and allows for a stealthy configuration. The two 10W OSRAM LEDs (20W total) provide intense lighting that spreads over a larger area than standard auxiliary lights, making the beam a true area light and minimizing hot spots from focused beams. Reduction of hot spots translates to clear images being sent through your reverse camera system when used at night or in dim environments as well as clear, not glaring lighting around the camp or worksite. Included with the ARB BASE Rack Auxiliary Light is 1 x 20W LED Light, 1 x Bracket to suit the ARB BASE Rack or Classic Racks, and both Male and Female DT connectors.
