A lamp for a vehicle includes a lamp housing part having an internal space to accommodate a light source, an outer lens part coupled to one side of the lamp housing part and to cover the internal space, and a vibration part fixed to the outer lens part. The vibration part includes a polarized piezoelectric element, and a first electrode and a second electrode provided to respectively face two opposite sides based on a direction in which the piezoelectric element is polarized. In response to a change in voltage over time being applied to the first electrode and the second electrode, the piezoelectric element outputs a sound. The piezoelectric element is in contact with and fixed to one side of the outer lens part.

A vehicle light is provided with a housing which partially delimits an interior and has an open side. A light source assembly is positioned inside the housing. An at least partially transparent outer lens is positioned on the open side of the housing. The outer lens is attached to the housing with a snap-fit assembly and a seal assembly to obtain a fluid-tight seal. The seal assembly contains a seal placed in a circumferential groove on the housing. The snap-fit assembly has a snap-fit component on the outer lens, which engages in the groove and is snapped onto the housing inside the groove. When fully assembled, the snap-fit component bears on the seal and the outer lens is releasably attached to the housing.

A headlamp unit includes: two low beam outer lenses that are arranged side by side on left and right at an interval and transmit a low beam forward; and a single high beam outer lens that is disposed on a right side with respect to a left end of one of the two low beam outer lenses that is disposed on a left side and, at a same time, on a left side with respect to a right end of one of the two low beam outer lenses that is disposed on a right side, is disposed above or below the two low beam outer lenses with a space, and transmits a high beam forward.

A running light for a vehicle includes at least one light source, a number of first optical waveguides on a first side, a number of second optical waveguides on a second side opposite the first side. One of the first waveguides emits light from the at least one light source in both the main beam direction, which runs along a main axis orthogonal to a secondary axis connecting the first side and second side, as well as in a first area toward the number of second waveguides. The second waveguide emits the light from the at least one light source in both the main beam direction and in a second area toward the number of first waveguides.

An automotive lamp is configured to emit a light beam with an adjustable cut-off line. The cut-off line is adjusted by altering a position of an inner lens within the automotive lamp.

A lighting device for a motor vehicle is disclosed, and may include at least one light source and a transparent cover through which the light generated by m the at least one light source passes and on which a flat layer having a plurality of discontinuities is provided. Any scattering of the light generated by the at least one light source caused by the layer may be greater than any scattering of the light generated by the at least one light source caused by the cover.
