ABSTRACT:
An extension bar with built-in light includes an elongate body having an open first end and an engaging recess in a second end of the elongate body. A switch member extends through a transverse hole of the elongate body and includes first and second conductive members connected thereto. A power supply unit and a light bulb are received in the passage. The second conductive member is in contact between the power supply unit and a conductive hand tool inserted into the engaging recess to activate the light bulb. The light bulb is also activated when rotating the switch member to contact directly the first conductive member, the second conductive member and the power supply unit.
