Abstract: A motor vehicle comprising a headlight lens having a monolithic body of transparent material, the monolithic body including at least one light entry face, a light passage section and at least one optically operative light exit face.

Abstract: To provide a semiconductor device including: a MOS transistor formed in a semiconductor substrate and have a threshold voltage to be adjusted, a replica transistor of the MOS transistor, a monitoring circuit monitors a gate/source voltage needed when the replica transistor flows a current having a given designed value, a negative voltage pumping circuit generates a substrate voltage of the MOS transistor, based on an output from the monitoring circuit, and a limiting circuit defines the operation of the negative voltage pumping circuit, regardless of a monitoring result of the monitoring circuit, in response to an excess of the substrate voltage with respect to a predetermined value.

Abstract: During acceleration and deceleration the front end of the body of a motor vehicle dips or rears on the suspension causing light beams from the headlamps to be directed upwards or downwards too much. To avoid this the orientation of a headlamp is variable by pivoting the lamp relative to the vehicle body, about a horizontal axis extending transversely of the body, in response to operation of an orientation control which responds to acceleration and deceleration.
