Abstract
A doorbell system comprises a doorbell chime (18), a first doorbell push (10) for sending a first input signal to the doorbell chime (18) in response to the first doorbell push (10) being activated, and a second device, such as a second doorbell push (14), for sending a second input signal to the doorbell chime (18). The doorbell chime (18) is arranged to emit light (24) of a first color in response to receiving the first input signal and light of a second, different, color in response to receiving the second input signal. The light (24) may be emitted around a perimeter of the doorbell chime, such that it creates a halo effect around the part of the door chime located within said perimeter.
