The construction of this piece of apparatus is mechani-cally substantial and from previous experience, the design of the latetype has been perfected so that its operation is highly current consumption of the arc is about amperes. In orderto facilitate the changing from one kind of lamp to the other, twopositive connection plugs are provided, the negative connection tothe car circuit being made through the hangers. Such a changecan also be effected by the alternative method of using a two-pointswitch, placed in the vestibule of the car. As the current can easilv be switched over so as to furnish either.
