ABSTRACT An electrical instrument to warn of impending roll-overs in vehicles such as farm tractors. By means of a hollow portion in the concave base of a sphere segment, having four convex walls, and four sets of electrical contacts with one free rolling ball acting as a switch. When the vehicle is at a dangerous angle, the ball passes the current from the first contact to the second of a set, and to the warning elements, the warning elements nullify false alarms, by means of a short time delay relay, wired to a horn and that to a warning light.
