A visual warning assembly for disposal at an intersection of a plurality of roadways is disclosed herein. The visual warning assembly includes a housing with first and second openings facing first and second directions. The first and second directions are transverse to one another. The visual warning assembly also includes a first light assembly positioned in the first opening and having a plurality of light emitting diodes arranged in pattern representing an emergency vehicle. The visual warning assembly also includes a second light assembly positioned in the second opening and having a plurality of light emitting diodes arranged in pattern representing an emergency vehicle. The visual warning assembly also includes a signal receiver physically supported by the housings or one or both of the first and second light assemblies. The signal receiver or sensor is operable to receive and communicate a signal emitted by a signal emitter associated with an emergency vehicle. The visual warning assembly also includes a controller physically supported by the housing or one or both of the first and second light assemblies. The controller is in communication with the first and second light assemblies and the signal receiver. In response to receiving the signal from the signal receiver, the controller is operable to selectively direct power to the first and second light assemblies from a power source such that only one of the first and second light assemblies is illuminated at any particular time to limit power consumption and heat generation by the visual warning assembly.
