<p>PROBLEM TO BE SOLVED: To improve the visibility of an indicating lamp by a large margin by composing the indicating lamp of a battery part and a light emitting part provided with a light emitting means and a control means, and making a bicycle travel to rotate the light emitting part so as to display a pattern by an after-image in human vision. SOLUTION: A light emitting part 2b and a battery part 2a are built in each storage part of a body and connected by a lead wire 5. The body is fixed to an axle of a bicycle being held between a fitting groove and a bracket 1. LEDs 2c to be a light emission source are connected to the light emitting part 2b. A light emitting hole 10 is provided on the base storage part surface of the body, and light emission of the LEDs 2c is easily visible through the light emitting hole 10. When a switch 14 is turned on, the light emitting part 2b is put in action, and the LEDs 2c blink at independent intervals to display a previously programmed pattern. The light emitting part 2b is rotated simultaneously with the rotation of the axle. At this time, a wheel appears as if the pattern were drawn thereon to the eyes of a person looking at the wheel from the side.</p> |
