The beacon has an attachment (1) with warning or indicator sign, which tips over when a motor vehicle drives over it. The lower end of the attachment is fastened to a foot plate (3) or directly to the road surface, via a pair of tilting joints (2). Each joint has a spring-loaded locking device. In a first locking position, the attachment is held in vertical position, and in a second locking position, the device locks the folded-down attachment. |
