PURPOSE:To enable to fit the title device easily without needing the selection of a fitting position, adjustment and wiring by constructing it such as to light up only in night running by the operation of a daylight switch and a seismoscope. CONSTITUTION:The title device is formed of a power battery 1, a daylight switch 4 for detecting whether the environment is light or dark and sending out signals, a seismoscope 5 for detecting the travel motion and the stop of a bicycle by its vibration and a main body for storing these and fitted in front of a basket or at a handle, and is constructed such as to light only in night running by the operation of the daylight switch 4 and the seismoscope 5. If a power switch 2 is switched on before night running, a lamp 7 is put off automatically in the light or at a temporary stop so that the battery is used economically as well as efficiently. Moreover, the title device can be fitted easily without needing special wiring at any place of the bicycle by building the seismoscope 5 in a light main body. |
