Abstract: An illuminated sign for use in a vehicle wash system, including a base, an upright member extending from the base and having an upper portion and a lower portion, and a head portion connected to the upper portion of the upright member. The illuminated sign includes at least one light source having a first mode and a second mode. The first mode is associated with a first group of vehicle wash services for treating an exterior of a vehicle. The second mode is associated with a second group of vehicle wash services for treating an exterior of a vehicle. The sign includes a sign controller in communication with the at least one light source. The sign controller is configured to enable the first mode in response to detecting a selection of the first group of vehicle wash services. The sign controller is also configured to enable the second mode in response to detecting a selection of the second group of vehicle wash services.

Abstract: A vehicle wheel washer comprising a pair of spaced-apart, mirror image, depending spray arms with spray heads mounted at the lower ends and directed inwardly toward the wheels of a vehicle which passes between the spray heads. The spray arms are mounted pendulum-type from an overhead pivotal support to move in unison between angular displacement positions thereby to follow the wheels of the vehicle being washed for a considerable linear distance to increase the effectiveness of the wheel cleaning operation. A bi-directional hydraulic actuator controls the positions of the pendulum arms in combination with gravitational force.
