The roof-mounted lighting device that can be activated automatically by train horn/gong and manually is called what?

Explanation:
A strobe light is the roof-mounted warning device designed to flash for visibility. It can be triggered automatically when the train horn or gong is sounded, and it can also be switched on manually by the crew when extra warning is needed. This combo of automatic and manual activation makes it a reliable visual alert for pedestrians and workers near the tracks. The other terms describe different things: a switch is a control for circuits, a general notice is an informational sign, and a train stop is a safety mechanism that stops the train rather than providing a lighting signal.
