Any idea what these are? I wondered if they were for warning of gaps, but they're only on one platform on the Met line at Baker Street - and they're all the way along.
They're strips of blue LEDs and about 2-3 feet long (from memory) and flash alternately. They're down the side of the platform and reflect slightly off the underside of the train, but I can't quite work out why?
