An apparatus for locational aiming of an overhead directional service unit includes a body including a first end configured to be matingly engaged with a housing assembly of the overhead directional service unit and a second end longitudinally opposed to the first end. A light source is disposed within the body and operable to project a light beam from the second end in a direction defined by a longitudinal axis of the body. With the first end matingly engaged with the housing assembly, pivotal movement of the body about a pivot axis relative to a mounting assembly of the overhead directional service unit applies a leverage force to the housing assembly to pivotally reposition the housing assembly relative to the mounting assembly so that the housing assembly is directionally aimed toward a target location visually indicated by the light beam.
