The '''Marshalite''' is a form of rotary [[traffic signal]] that was designed by [[Charles Marshall (engineer)|Charles Marshall]] in 1936.<ref name=vicmusem1>[http://museumvictoria.com.au/discoverycentre/Infosheets/Caring-for-the-things-we-keep/ Caring for the Things We Keep]; conservation of the "working" Marshalite pictured above, from the Victoria Museum.</ref> It consists of two rotors pointing at coloured sections that denoted whether traffic in either direction should proceed, prepare, or stop. Variations exist for [[pedestrian crossings]] with additional text instructing crossers to "Walk" or "Don't Walk". The last Marshalite to exist before they were removed in the 1970s was along the [[Nepean Highway]], in [[Victoria (Australia)|Victoria]], [[Australia]].
A similar system was used in Europe, i.e. in the Netherlands, Austria (Vienna) and (West-)Germany. In Germany it was called "Heuerampel" (named after the engineer Josef Heuer) and used in a number of places until 1972, when a change in traffic laws outlawed them. For historic reasons one of them is still in place (though unused) in [[Bochum]].
With the Marshalite, drivers have a clear indication of when the signals will change though the exact point of change is not clear.
At the intersection of Whitehorse Road and Union Road<!--Surrey Hills VIC--> in 1969 the clock was used in conjunction with lights so that the point of change was absolute and unambiguous.<ref name=vicmusem1 /> However the clock provided advance warning of each impending change.
