Section 46(48) in The Port Rules for the Port of Bombay
(48)-(49) The "Come On" signal for a vessel to enter dock at night will be morsed to the vessel concerned from the dock. At Prince's and Victoria Docks the "Come on" signal will be sent from either the Dock Master's chowki at Victoria Dock entrance or the flag staff on the Island Tower. The position from which this signal is sent will not indicate the dock to which the vessel is to proceed. The pilot will already have this information on the Pilot Order.
