AP184CA 13 Abstract of the Disclosure A warning device for incorporation in the handle-bar of a bicycle has a casing with a tubular portion and a head portion. The tubular portion fits inside the end of the handle-bar while the head portion abuts the end of the handle- bar. A flat spring member with an arc like configuration extends longitudinally outside the tubular portion to engage the inside of the handle bar and retain the casing in its installed position. There is a battery cell within the tubular portion as well as circuitry. A piezoelectric transducer mounted inside the head portion is connected to the circuitry to form an oscillatory circuit. A switch is mounted externally of the head portion, preferably extending back over the end of the handle bar. One side of the switch is connected through the spring member to one side of the cell and the other side of the switch is connected to the oscillatory circuit. Closing of the switch supplies power to the oscillatory circuit causing the transducer to generate a warning sound.
