Intrigued as to what the pictured sensor is - there seems to be one in every coach on the Pendolino. Are they light level sensors? If so how do they differentiate between internal and external lighting?
Thanks.
(Picture is an odd round sensor mounted in this case on the end of the pantograph well of Coach U, but they are on coach ends in other coaches)
