Light and Motion ARC Li-ion ULTRA HID High Intensity Discharge Bike Light System. Complete with all the parts including bike & helmet mounts and instruction manual. This is an incredible light, the beam and amount of light this casts is amazing. Really good for country lane and off road riding. Photos don't do it justice. From a smoke and pet free home. I have now stopped riding my bike, please see my other listings (to be put up soon).
