A vehicle lamp includes a laser light source that is able to emit laser light and emits laser light generated by the laser light source forward from an emission end, and an optical mechanism that performs scanning with the laser light and depicts a figure in an irradiation destination.

A vehicle headlamp includes a plurality of light emitting elements; a plurality of first lenses; and a plurality of second lenses. The first lens includes a first lens entrance and a first lens exit, and is configured to converge light entered the first lens entrance from the light emitting element on the first lens exit. The second lens includes a second lens entrance facing the first lens exit of the first lens and the second lens exit having a projection shape for forming a focal point. The focal point of the second lens is positioned at a side of the second lens ahead the first lens exit of the first lens.

A light source device using a polarity of a material may include a transparent frame forming an inner space accommodating a nonpolarity material and a polarity material; a light source portion irradiating light through the nonpolarity material or the polar material accommodated in the transparent frame; and an electromagnet configured to switch respective positions of the nonpolarity material and the polar material by a magnetic force generated as a current is applied from outside of the light source device.

When a power supply voltage is supplied to an input terminal, a first constant current driver supplies a first driving current to the anode of a first semiconductor light source. A first switch is provided between the first semiconductor light source and a second semiconductor light source, and a second switch between the first semiconductor light source and a third semiconductor light source. When a switching terminal has a high impedance or low level, a switching circuit turns the first switch on and the second switch off. When a switching voltage is supplied to the switching terminal, the switching circuit turns the first switch off and the second switch on, and supplies a second driving voltage smaller than the first driving current to the second semiconductor light source.
