摘要

Device for producing an acoustic signal into a function of the light - or color change of a light source of a variable light - signal installation (a), characterized by– a with a light sensor (3) is equipped with optical signal receiver (4),– a in the case of light - or color change of the installation (a) of the optical signal receiver (4) controlled, and an acoustic signal generating unit (6 or 6’),– a the light sensor (3) and the optical signal receiver (4) containing housing (1), and– a attached to said housing and on the installation (a) to be secured to the device (2) for shielding of the light source of the traffic light (a) and of the light sensor (3) against external interfering light
