1. A convertible lighting device comprising:a battery housing having at least one side portion, a bottom portion and a top portion defining a battery compartment which receives at least one battery; a first mounting port disposed on said battery housing, said first mounting port including first and second electrical contacts that are electrically connected to said at least one battery; a second mounting port disposed on said battery housing, said second mounting port including third and fourth electrical contacts and electrically connected to said at least one battery; a removable lamp assembly having a collar, arms connected to said collar, and a lamp housing pivotally mounted between said arms; fifth and sixth electrical contacts fixed to said collar, said fifth and sixth electrical contacts electrically connected to at least one lamp disposed in said lamp assembly; and switching means electrically connected between said at least one battery and at least one lamp to modulate power delivery from said at least one battery to said at least one lamp; wherein said lighting device is operated in a flashlight mode when said lamp assembly is connected to said first mounting port; and said lighting device is operated in a headlamp mode when said lamp assembly is connected to said second mounting port. 2. The convertible lighting device of claim 1, wherein said battery housing has three sides.3. The convertible lighting device of claim 1, wherein said first mounting port is located at said top portion, and said second mounting port is located at said at least one side portion.4. The convertible lighting device of claim 1, wherein said top portion is hingedly connected to said at least one side portion.5. The convertible lighting device of claim 1, wherein said battery compartment holds three batteries.6. The convertible flashlight of claim 1, further comprising a screw connected to said collar; andsaid first and second mounting ports further comprising threaded receptacles for receiving said screw. 7. The method of claim 1, wherein said first and second mounting ports each comprise orientation receptacles; andsaid collar comprises orientation tabs. 8. The method of claim 1, wherein said at least one lamp is a light emitting diode.9. The convertible light device of claim 1, wherein said switching means is located in said lamp housing.10. The convertible light device of claim 9, wherein said switching means further comprises a flexible ceiling.11. The convertible light device of claim 10, wherein said flexible ceiling comprises an ovate or circular diaphragm integrally formed and centrally disposed in said lamp housing.12. The convertible light device of claim 11, wherein said flexible ceiling has an external surface decorated by concentric grooves and ridges to enhance manual engagability and flexibility of said flexible ceiling.13. The convertible light device of claim 1, further comprising a reflector disposed in said lamp housing.14. The convertible light device of claim 1, wherein said switching means comprises a multi-function control device having selectable control means to connect and disconnect power from said at least one battery to said at least one lamp and to select between a plurality of operational modes of said at least one lamp.15. The convertible light device of claim 14, wherein said selectable control means includes a manual switch to control an on-off mode of said at least one lamp and an analog control circuit to control a second operational mode of said at least one lamp.16. The convertible light device of claim 15, wherein said second operational mode of said at least one lamp is a flashing mode, and wherein said analog control circuit comprises a flasher circuit electrically connected to said at least one lamp comprising a switching transistor serially connected between said at least one battery and said at least one lamp and a switching transistor control network including a control transistor and a resistor-capacitor network functionally interconnected to effect a controlled flashing operational mode of said at least one lamp.17. The convertible light device of claim 14, wherein said selectable control means includes a microprocessor functional to control at least one operational mode of said at least one lamp.18. The convertible light device of claim 17, wherein said at least one operational mode is a flashing mode, a brightening mode, a dimming mode, a battery protection mode, or an auto-off mode.19. The convertible light device of claim 18, wherein said microprocessor further controls a cycle rate or intensity of said at least one lamp within a selected operational mode.20. The convertible light device of claim 19, wherein said microprocessor controls a brightening or dimming mode having at least two selectable lamp intensity options, a flashing mode having at least two selectable lamp flashing rate options, and an auto-off mode functional to automatically terminate power to said at least one lamp after a predetermined time of operation.
