Abstract
An optical unit includes a first light source, a second light source, a rotary reflector that rotates about an axis of rotation while reflecting first light emitted from the first light source, and a projection lens that projects the first light reflected by the rotary reflector into a light illuminating direction of the optical unit to form a first light distribution pattern. The second light source is disposed such that second light emitted from the second light source enters the projection lens without being reflected by the rotary reflector. The projection lens is configured to project the second light into the light illuminating direction of the optical unit to form a second light distribution pattern such that the second light distribution pattern overlaps an end portion of the first light distribution pattern in a right-left direction.
