ABSTRACT OF THE DISCLOSURE A visual warning system for a locomotive is dis- closed which includes a signal unit mounted on the locomotive and connected by sensing means to an audible warning device on the locomotive, such as a horn. The visual warning signal unit is thus actuated whenever the horn is sounded. The signal unit comprises a stroboscopic-type lamp assembly and flashing circuitry with a coating of luminescent material surrounding the lamp to extend the perceived duration of each flash of the lamp. The system may also include a delay for maintaining the flashing of the visual warning signal unit after the horn has been deactuated.
