+### TA4 Ampel / TA4 Traffic Light
 
+Die TA4 Ampel gibt es in zwei Ausführungen: in schwarz (europäische Version) und in gelb (amerikanische Version). Zusätzlich gibt es
+einen Mast, einen Arm und einen Verbinder-Block. Die Ampel kann auf oder an einen Mast montiert werden. Sie kann aber nicht
+an einen Arm montiert werden. Dies hat technische Gründe. Dafür gibt es den Verbinder-Block, der zwischen Arm und Ampel gesetzt wird.
 
+Die Ampel kann über Kommandos wie beim TA4 Signal Tower angesteuert werden.
+Wird zusätzlich der TA4 Spieler Detektor eingesetzt, so kann die Ampel auch auf Fußgänger oder Fahrzeuge reagieren.

+### TA4 traffic light
 
+The TA4 traffic light is available in two versions: black (European version) and yellow (American version). In addition, there is a mast, an arm and a connector block. The traffic light can be mounted on or to a mast. However, it cannot be mounted to an arm. This is for technical reasons. This is why there is the connector block, which is placed between the arm and the traffic light.
+
+The traffic light can be controlled using commands like the TA4 signal tower. If the TA4 player detector is also used, the traffic light can also react to pedestrians or vehicles.
+
+The traffic light does not require any electricity.
