ABSTRACT:
A pen light has a removable dental mirror positioned to be in the beam of the light. The flashlight has a barrel which is constricted on one end to capture and hold a pen light bulb dropped in the other end. The electrical circuit within the flashlight includes a strip spring with a bow or arched section which make contact with the base of a flashlight bulb of almost any type and with many different sizes, on a bulb drop-in basis. The electrical contacts are such that the batteries may be dropped either end first into the barrel of the flashlight. The off-on switch has a threaded screw so that the light is switched off and on by turning a screw.
