1. A vehicle lamp comprising:
a projection lens;
a low beam light source module; and
a high beam light source module, wherein
the projection lens is divided into a plurality of lens areas, each of which has a different focal point position, and one of the plurality of lens areas is a low lens area with a focal point where parallel light incident from a front surface of the projection lens is converged,
the low beam light source module has a low beam light source and a reflector which reflects emitted light from the low beam light source, and is set such that reflected light from the reflector is incident on a back surface of the low lens area, and a low beam light distribution is emitted from an area front surface, and
the high beam light source module has a high beam light source, and is set such that emitted light from the high beam light source is directly incident on a lens back surface of the projection lens, and a high beam light distribution for each of the plurality of lens areas is emitted from each of a plurality of area front surfaces,
wherein the projection lens is divided into at least a first lens area, a second lens area, and a third lens area from a top as a plurality of high lens areas where the emitted light from the high beam light source is directly incident, and
the second lens area of the projection lens is the low lens area where the reflected light from the reflector is incident, and
wherein
in the projection lens, an area further below the third lens area, or a lower area obtained when the third lens area is divided into an upper part and a lower part is a fourth lens area that forms an upper light distribution of a high beam light distribution pattern.
