The torches are standard kit on most commercial aircraft, and there is normally one by each jumpseat. The mounting is a charger and certainly the airlines I've worked for, part of the per flight SEP checks is that you check the red LEDs on the torches flash at least once every ten seconds. Simply removing the torch from the stowage switches them on, replacing them (or unscrewing the battery) switches them off. If the LED isn't flashing indicated they're not charging, and should have been picked up pre flight.
