Semaphores
Block signals; when "on", the semaphore is presented as follows: Stop: a red rectangular arm with a white vertical stripe extended horizontally with a red light so that it can be seen at night. Caution: a yellow rectangular arm with a black chevron and a fish-tail end with a yellow light so that it can be seen at night. When in the "off" position, the arm is raised. At night or when visibility is poor, a green light is shown.
