A lighting assembly for use in a cigarette lighter shell (12). The lighting assembly comprises an insulative case (38) for housing a power supply, such as batteries (52,54), and conductors (40,42,44,46) for establishing an electrical circuit that includes the batteries (52,54), the conductors (40,42,44,46), a light bulb (48), and the cigarette lighter shell (12). A reflector (50) and lens (62') may be provided to focus and direct the beam generated by the bulb (48). A resilient portion of one of the conductors (46) is biased against a well (30) of the cigarette lighter shell (12) to close the electrical circuit. When a lid (18) of the cigarette lighter shell (12) is closed, the lid (18) engages an insulative tip (88) to remove the conductor from contact with the shell wall (30) and turn the flashlight off. The tip (88) is provided on an end of the conductor (46) and may be manually manipulated to remove the conductor (46) from contact with the shell wall (30) to open the electrical circuit and place the flashlight in an unlocked off position. A groove (90) may be provided in the case (38) to receive the tip (88) and maintain an open circuit to place the flashlight in a locked off position.
