A vehicle lamp can include a plurality of light source modules each having
an LED as a light source, and optical systems for distributing light from
each of the light source modules frontward toward predetermined areas or
predetermined patterns that are different from each other and which make
up a light distribution pattern. Each of the optical systems can be
optimized to emit light to a predetermined area, and each of the light
source modules' LEDs can be optimally arranged for each of the
corresponding optical systems.
