These signs must be internally electrically illuminated or self-illuminated by other than electrical means and must have an initial brightness of at least 400 microlamberts. The colors may be reversed in the case of a sign that is self-illuminated by other than electrical means.

Subpart D : Design and Construction
(1)
After leaving the passenger seat, visually identify the emergency escape path along the cabin aisle .oor to the .rst exits or pair of exits forward and aft of the seat; and
(2)
Readily identify each exit from the emergency escape path by reference only to markings and visual features not more than 4 feet above the cabin .oor.
(f)
Except for subsystems provided in accordance with paragraph (h) of this section that serve no more than one assist means, are independent of the airplane’s main emergency lighting system, and are automatically activated when the assist means is erected, the emergency lighting system must be designed as follows :
(1)
The lights must be operable manually from the .ight crew station and from a point in the passenger compartment that is readily accessible to a normal .ight attendant seat.
(2)
Theremustbea .ightcrewwarning lightwhichilluminateswhenpowerison in the airplane and the emergency lighting control device is not armed.
(3)
The cockpit control device must have an ”on,” ”o.,” and ”armed” position so that when armed in the cockpit or turned on at either the cockpit or .ight attendant station the lights will either light or remain lighted upon interruption(except aninterruption causedby a transverse vertical separation of the fuselage during crash landing) of the airplane’s normal electric power. There must be a means to safeguard against inadvertent operation of the controldevicefromthe ”armed” or ”on” positions.
