An assembly for creating the appearance of flames emerging from a vehicle exhaust, including a partially transparent tube connected to the vehicle, a light emitting array positioned within the tube, a plurality of reflective generally flame-shaped streamers extending at least partially into the partially transparent tube, an air pressure source operationally connected to the tube, a power source electrically connected to the light emitting array and an electronic controller operationally connected to the light emitting array. Actuation of the air pressure source waves the streamers within the tube and the streamers are visible through the tube when waving. The light emitting array is positioned to shine light onto the waving streamers and the electronic controller is operable to sequence the actuation of the light emitting array.
