25650.5
. Every motorcycle manufactured and first registered on and
after January 1, 1978, shall be equipped with at least one and not
more than two headlamps which automatically turn on when the engine
of the motorcycle is started and which remain lighted as long as the
engine is running. This section does not preclude equipping
motorcycles used as authorized emergency vehicles with a switch to be
used to turn off the headlamp during emergency situations or when
the light would interfere with law enforcement, if the switch is
removed prior to resale of the motorcycle.
