Abstract

A visual and audible warning device has a piezoelectric element operable to cause vibrations which are transmitted through a light transmitting member, and a light emitting element which upon actuation causes a visual warning to be transmitted through the light transmitting member. The visual and audible warnings transmitted by the light transmitting member are intended to attract the attention of the operator of a vehicle, such as a boat, above the sound of the engine or other noise. The device has circuit means coupled with the piezoelectric element and the light emitting element for causing a predetermined electrical signal to be applied to the piezoelectric element and causing energization of the light emitting element upon actuation. The device may include a housing having support portions for supporting the light transmitting member and one or more light emitting elements in position while sealing the light transmitting member and electronic components within the housing from the ambient atmosphere, including weather elements which may otherwise result in corrosion and failure of the device.
