Headlight unit for single-track two-wheeled vehicles

A headlight unit for a single-track two-wheeled vehicle, which experiences an inclination around its longitudinal axis (X) while negotiating a curve, the headlight unit comprising:

• a central headlight oriented straight ahead to illuminate straight-ahead of the vehicle;
• a right lateral headlight mounted right of the central headlight, mounted turned downward around its optical axis by an inclination angle (β) to compensate for inclination, and mounted facing leftwards to illuminate a left-hand curve wherein a right portion of an outside rim is disposed out of plane with respect to the central headlight;
• a left lateral headlight mounted left of the central headlight, mounted turned downward around its optical axis by the inclination angle (β) to compensate for inclination, and mounted facing rightwards to illuminate a right-hand curve wherein a left portion of an outside rim is disposed out of plane with respect to the central headlight;
• a sensor-controlled correction device in communication with all headlights to generate a light-beam pattern, the correction device comprising an electronic control unit,
• wherein when the vehicle is substantially upright, the correction device switches the central headlight to full illumination and the lateral headlights to reduced illumination;
• and
• wherein when the vehicle is negotiating the curve having a minimum roll angle (α), the correction device switches the central headlight to reduced illumination and one of the left and right headlights to full illumination.
