Claim:
A faucet light-effect module for mounting onto the water outlet of a faucet; comprising a housing, a battery cover, an electro-magnetic control module, a spring switch and a light-emitting device, characterized in that the housing includes an inner and an external wall forming a cavity area for holding batteries and a water passage area having a water outlet, said water outlet is loudspeaker shaped with a slanting edge mounted with at least one light-emitting device, said battery cover being mounted onto a battery compartment of the module and is sealed with water resistant rubber rim, the electro-magnetic control module being mounted in said cavity, said module including a paddling rod, a restoration rod, and a magnetic device, wherein the paddling rod is extended from a center shaft of the magnetic device and a front end of the paddling plate is positioned in said water passage area which is directly in contact with a water stream, whereby the paddling plate is rotated by the water stream which simultaneously drives the magnet element to change its' polarity, the restoration rod restores the polarity of the magnetic device when the water stream stops flowing: said spring switch is positioned in said cavity and directly accepts changes of the polarity and restoration effected by the magnetic device to form a switch supply of power from said battery.
