Section 11(5) in The Merchant Shipping (Crew Accommodation) Rules, 1960
(5)In every ship to which these rules apply, an electrical system shall be installed which is capable of providing adequate lighting in every part of the crew accommodation. The electric lights shall be so arranged as to give the maximum befit to the crew, and in particular, an electric reading light shall be fitted at the had of each bed and shall be capable of being switched on and off from the bed. A lamp emitting at least 200 lumens shall be fitted in every such reading light in a sleeping room, and a lamp emitting at least 400 lumens shall be fitted in every such light in a hospital ward. An efficient alternative system of lighting source of electric power shall be always available for lighting the crew accommodation. The Central Government may exempt any ship of under 500 tons from the requirements of this sub-rule if it is satisfied that compliance therewith is unreasonable or impracticable in the circumstances and that other suitable artificial lighting is provided in the crew accommodation.
