What is claimed is: 1. A bicycle lighting device comprising: a lamp case having a light source non-adjustably fixed in position therein, the lamp case having a first mating surface; a control case having a second mating surface, the control case being pivotally connected to the lamp case by a hinge

What is claimed is: 1. A bicycle lighting device comprising: a lamp case having a light source non-adjustably fixed in position therein, the lamp case having a first mating surface; a control case having a second mating surface, the control case being pivotally connected to the lamp case by a hinge such that the first and second mating surfaces clamp onto a portion of a bicycle, the control case having a control circuit for controlling the light source; and a mounting unit including a non-metallic elastically deformable flexible member mounted to one of the lamp case and the control case, the flexible member being removably attachable to the other of the lamp case and the control case such that with the flexible member attached to the other of the lamp case and the control case the flexible member draws the lamp case and the control case toward each other providing a clamping force urging the first and second mating surfaces to clamp to the portion of the bicycle. 2. The bicycle lighting device as recited in claim 1, wherein the light source includes at least one light emitting diode. 3. The bicycle lighting device as recited in claim 2, wherein the light source includes two light emitting diodes that are positioned one over another. 4. The bicycle lighting device as recited in claim 2, wherein the mounting unit includes an engaging part provided on one of the lamp case and the control case, and a force applying member provided on the other of the lamp case and the control case configured to engage with the engaging part and configured to apply the clamping force in a direction so as to cause the lamp case and the control case to draw closer together. 5. The bicycle lighting device as recited in claim 1, wherein the portion of the bicycle includes a handlebar and the lamp case is configured such that the lamp case shines light in front of the bicycle. 6. The bicycle lighting device as recited in claim 5, wherein the first mating surface has an arcuate shape for mating with a handlebar of the bicycle. 7. The bicycle lighting device as recited in claim 1, wherein the control case has an on-off switch positioned at a side of the control case that faces rearwardly relative to the bicycle. 8. The bicycle lighting device as recited in claim 7, wherein the second mating surface has an arcuate shape for mating with a handlebar of the bicycle. 9. The bicycle lighting device as recited in claim 8, wherein the control case has a battery case configured to house at least one battery to serve as a power source for the control circuit and the light source. 10. The bicycle lighting device as recited in claim 7, wherein the control case has a battery case configured to house at least one battery to serve as a power source for the control circuit and the light source. 11. The bicycle lighting device as recited in claim 1, wherein the first mating surface on lamp case has an arcuate shape for mating with a handlebar of the bicycle and the second mating surface on the control case has an arcuate shape for mating with a handlebar of the bicycle. 12. The bicycle lighting device as recited in claim 1, wherein the control case has an electric power input part configured for receiving electric power from an alternating-current electric generator on the bicycle. 13. The bicycle lighting device as recited in claim 12, wherein the electric power input part has an electric power supply cable that protrudes from the control case to an outside and is configured such that the electric power supply cable is connected to the alternating-current electric generator. 14. The bicycle lighting device as recited in claim 13, wherein the electric power supply cable includes a shielded coaxial cable. 15. The bicycle lighting device as recited in claim 14, wherein the control circuit has a rectifier circuit configured to convert the electric power from the alternating-current electric generator into direct current. 16. The bicycle lighting device as recited in claim 13, wherein the control circuit has a rectifier circuit configured to convert the electric power from the alternating-current electric generator into direct current. 17. The bicycle lighting device as recited in claim 12, wherein the control circuit has a rectifier circuit configured to convert the electric power from the alternating-current electric generator into direct current. 18. The bicycle lighting device as recited in claim 17, wherein the control circuit has an electric energy storage element configured to store direct-current electric power from the rectifier circuit. 19. The bicycle lighting device as recited in claim 1, wherein the control case has a battery case configured to house at least one battery to serve as a power source for the control circuit and the light source. 20. The bicycle lighting device as recited in claim 1, wherein the mounting unit includes an engaging part provided on one of the lamp case and the control case, and a force applying member provided on the other of the lamp case and the control case configured to engage with the engaging part and configured to apply the clamping force in a direction so as to cause the lamp case and the control case to draw closer together. 21. The bicycle lighting device as recited in claim 1, wherein the mounting unit including an elastic member positioned on the second mating surface of the control case such that with the control case and lamp case clamped about the portion of the bicycle, the elastic member engages the portion of the bicycle. 22. The bicycle lighting device as recited in claim 1, wherein the flexible member is an O-ring. 23. The bicycle lighting device as recited in claim 1, wherein the mounting unit is configured and arranged such that the clamping force is sufficient to prevent the lamp case and the control case from rotating relative to the portion of the bicycle, but a lighting angle of the lamp case is adjusted easily by manually applying a force larger than the clamping force in order to move the lamp case and the control case relative to the portion of the bicycle.
