Abstract
A visual signal system including a signal display carried prominently on a paving machine, where it can be seen clearly by an operator of a dump truck or shuttle vehicle delivering paving material to the paving machine, as well as by other nearby personnel. Control circuits provide that a paving machine operator may separately control the display of certain signals, while other signals are automatically presented on the signal display in response to operation of paving machine functional controls.
