A device for forming a dynamic image on an aircraft sign includes a plurality of light sources, an input power line, a first timer and a second timer both connected to an enable input and a plurality of delay circuits each connected to a different one of the light sources. The system also includes a counter having a plurality of counter outputs, the counter receiving a counting pulse from the first timer in a dynamic mode of operation and disable signal from the second timer after expiration of a preset time, the expiration of the preset time causing the device to transfer from the dynamic mode to a static mode where each of the plurality of light sources are simultaneously illuminated.

Dual mode aircraft indicator sign

An aircraft light, particularly for emitting light onto a runway during takeoff or landing and/or onto the ground during taxi, comprises a light source (), a reflector (), a support frame () for the reflector (), and an adjustable bearing arrangement () including at least two joints () pivotably supporting the reflector (). The adjustable bearing arrangement () comprises at least one extendable and retractable adjustment element () guided at the support frame () along a movement axis (). At least one of the two joints () is formed as a ball-type joint. The ball-type joint (), to compensate for a change of the distance (A,A') between the at least two joints () of the bearing arrangement () upon movement of the adjustment elements () for tilting the reflector (), slidably engages the reflector substantially orthogonal to the movement axis () of the adjustment element.
