A light for use with an oral anesthesia syringe that is received into a passageway of a barrel of the light. When the syringe is received into a first opening in a proximal end of the barrels passageway, the needle of the syringe extends through a second opening at the proximal end of the barrel. At least one lamp and preferably a plurality of lamps at the distal end of the barrel illuminate the needle and the interior of a patients mouth. A battery is included in the light for powering the lamps. The insertion of the syringe into the barrel closes a pair of contacts to cause the battery to power the lamps, or the battery may be removed to remove power from the lamps.
