Abstract
An indicator system connected with a guide wheels steering hydraulic cylinder and informing a vehicle operator about the guide wheel angular position relative to the vehicle rectilinear travel direction under any weather, terrain or light conditions. Right and left contact plates located along one selection of the outer surface of the cylinder are contacted by a contact arm moving with the piston rod of the cylinder. Since the rod reciprocates depending on the direction of turning the contact is used to complete a circuit lighting a left or right turn lamp, thus indicating when a predetermined turn angle is exceeded in either direction.
