An apparatus at a spinning room machine, especially a spinning preparation machine, for example a carding machine or draw frame, for visual signal display, has at least two light sources in the form of light-emitting diodes (LEDs), each of which is associated with a cover, the signal display-which is in communication with a control device-being capable of emitting signals of light of different colours. In order to provide an apparatus which especially is of simple construction and allows a reduced outlay in terms of manufacture and installation, a plurality of light-emitting diodes or lighting means, which are located inside a clear or opaque cover, are capable of emitting coloured or white light corresponding to the particular operating situation of the spinning room machine.
