A motorcycle headlamp capable of emitting a light beam with a beam pattern calculated to provide optimum forward illumination. In order to maintain the beam pattern in a level position about the lamp axis despite the lateral tipping of the motorcycle, at least one road sensor is employed for detecting the lateral angular position of the vehicle with respect to the road surface by transmitting radiation such as an ultrasonic wave or infrared rays toward the road surface and receiving its reflection from the road surface. Electric signals representative of...
A beam pattern leveling headlamp system for use on a motorcycle or like vehicle that is subject to lateral tipping as when taking a curve, the headlamp system comprising: (a) a headlamp unit on a vehicle for throwing a light beam having a prescribed beam pattern, the headlamp unit having a lamp axis and being capable of angularly displacing the beam pattern about the lamp axis; (b) beam pattern leveling means acting on the headlamp unit for causing the same to angularly displace the beam pattern about the lamp axis; (c) vehicle inclination detector means...
