On traffic_signals, the sections on signal types have the option for sound-based signals or vibration-based signals for different kinds of impairment. I can’t seem to find, however, movable or animated signals that can be used for eg.: colour blindness (esp. red-green in this case) and, presumably, as a further assistance for deafness.
The ones I know of consist of a “go” signal for pedestrians that presents a walking animation for the go turn or flash different parts of the “legs” in a loop. I would assume there are other kinds somewhere. Do we have this?
