The light deflection device is configured to switch a first reflection position and a second reflection position in at least some region of the reflection part. The first reflection position is a position at which the light irradiated by the irradiation optical system is to be reflected toward the projection optical system so as to be effectively used as a part of a desired light distribution pattern. The second reflection position is a position at which the light irradiated by the irradiation optical system is to be reflected so as not to be effectively used. The detection unit is arranged at a position at which the light reflected at the second reflection position by the light deflection device can be detected.

A configurable vehicle lighting module system includes a shared lens configured to provide a first light pattern for a first vehicle lighting function and a second light pattern for a second vehicle lighting function. The shared lens includes a mounting axis which provides a reference for mounting the shared lens on a vehicle. First internal optics are configured to direct light toward the shared lens to provide the first light pattern, and second internal optics are configured to direct light toward the shared lens to provide the second light pattern. A coupling system is configured to join the shared lens with either the first internal optics to form a first module configuration for providing the first vehicle lighting function, or with the second internal optics to form a second module configuration for providing the second vehicle lighting function. The shared lens conceals physical differences between the first and second internal optics such that the first and second light module configurations have the same appearance when viewed along the mounting axis of the shared lens.

A device including at least one semiconductor component connected to an electrical connection element, the electrical connection element is attached to a heat sink and connected to a group of electrical wires, the group being linked mechanically and electrically to the electrical connection element by a single connector, the group being linked to the heat sink by holding means.

An optical unit includes a light source and a rotary reflector configured to reflect a light emitted from the light source and rotate around a rotation axis in one direction. The rotary reflector is provided with a reflective surface such that a desired light distribution pattern is formed by scanning a light of a light source reflected by the rotary reflector while the rotary reflector is rotated. The light source includes a first light-emitting portion configured to be turned on when forming a first light distribution pattern that mainly illuminates a range lower than a horizontal line, and a second light-emitting portion configured to be turned on when forming a second light distribution pattern that illuminates a range at least higher than the horizontal line.

An illumination device includes a case, a lens body, an LED substrate, a stopper member, and a lead wire. The lens body is fixed in the case. An illuminating part of the lens body projects outward from the upper face opening of the case. The LED substrate is housed in the substrate housing part of the lens body, and the lower surface of the LED substrate is supported by the stopper member. The two lead wires are connected to the LED, led out of the case through insertion holes in the stopper member, and retained by one of lead wire retainers formed on the two side surfaces of the case.

A lamp assembly for a vehicle comprising a housing, a reflector mounted in the housing, a light source, a printed circuit board or PCB mounted on a heatsink of the lamp assembly and coupled to the light source to control operation of the light source. The PCB has a first connector for coupling to a second connector comprising a body having a plurality of resilient or elastic arms that each have a detent for locking the connector to the component and retain electrical contact with the PCB. The wall of the heatsink defines an aperture for receiving the second connector and provides a locking surface that deflects the arms towards the body while engaging and cooperating with the detests to lock the connector to the PCB. The free end of the arms extend beyond the mounting wall and are actuated to unlock the connector from the PCB.
