Power to the robots does not shut off until someone hits the robot main breakers; however, all robots are disabled after the match. Disabled means that all the outputs controlled by the RoboRIO (AKA, all the outputs!) are shut off. There are no particular rules stating that stuff not controlled by the RIO has to shut off when the robot is disabled; after all, those items have no way of knowing that the robot is disabled. You'll typically see that on LED strips or targeting flashlights/ring lights that are "constant on", or on lights that are controlled by a Spike relay that is set to stay/go on when disabled. Not uncommon to see some lights on until main breakers are hit.

The "Safety" light is actually the RSL, Robot Signal Light. Its primary function is to display what the robot status is, not to be a safety light per se. As I recall, it goes solid (NOT off) at the end of the match, or when the robot is disabled, but it has several possible states that help field staff troubleshoot problems.
