(b) In the case of aeroplanes with an MOPSC of more than 19, the emergency lighting system, referred to in (a) shall include:
(1) sources of general cabin illumination;
(2) internal lighting in floor level emergency exit areas;
(3) illuminated emergency exit marking and locating signs;

(c) For aeroplanes with an MOPSC of 19 or less and type certified on the basis of the Agency's certification specification, the emergency lighting system referred to in point (a) shall include the equipment referred to in points (1), (2) and (3) of point (b).
(d) For aeroplanes with an MOPSC of 19 or less that are not certified on the basis of the Agency's certification specification, the emergency lighting system referred to in point (a) shall include the equipment referred to in point (b)(1).

EASA regulations mandate emergency lighting systems with independent power for larger airplanes (over nine passengers) to aid evacuation. Planes with more than 19 seats require enhanced lighting, including exit signs and floor-level paths. Smaller planes have varied requirements based on certification date, ensuring cabin illumination for nighttime operations.
