A lighting assembly for use in a cigaret lighter shell is disclosed. The lighting assembly comprises an insulative case for housing a power supply, such as batteries, and conductors for establishing an electrical circuit that includes the batteries, the conductors, a light bulb, and the cigaret lighter shell. A reflector and lens may be provided to focus and direct the beam generated by the bulb. A resilient portion of one of the conductors is biased against a wall of the cigaret lighter shell to close the electrical circuit. An insulative tip is provided on an end of the conductor and may be manually manipulated to remove the conductor from contact with the shell wall to open the electrical circuit and place the flashlight in an unlocked off position. A groove may be provided in the case to receive the tip and maintain an open circuit to place the flashlight in a locked off position. When a lid of the cigaret lighter is closed, the lid engages the tip to remove the conductor from contact with the shell wall and turn the flashlight off.
