| 1. A tool adapted to act on a work surface comprising:
a tool portion; and
a light generating device portion comprising:
a self-leveling pendulum assembly including a pendulum pendulously suspended within the light generating device;
a light source fixed to the pendulum, wherein the light source generates light directed along a first pathway;
a light redirection assembly capable of moving from a first position to a second position to selectively redirect the light
from the first pathway to a second pathway;
a lock mechanism operable to secure the pendulum and prevent its pivotal motion; and
an actuator operable to selectively engage and disengage the lock mechanism and to selectively activate and deactivate the
light source.
