A system for adjusting the headlamp of a motor cycle as the motor cycle adopts an inclined position when traversing a curve, in such a way that the effect of the motor cycle inclination on the headlamp beam attitude is substantially compensated. The magnitude of the inclination of the motor cycle is detected by an acceleration transducer comprising a mass movable under the control of a spring, in a direction which is generally vertical while the motor cycle is upright. The direction of the inclination of the motorcycle is detected by a gyroscope system; more specifically, a rate gyroscope is used, which provides a signal only when the inclination of the motor cycle is actually changing. A logic circuit is provided to maintain an indication of whether the motor cycle is leaning to the left or the right when the inclination of the motor cycle has ceased to change. |
