There is a type of strip lighting on a lot of B737's that is called "Photoluminescent" - that is Glow in the Dark lighting - and as a result, it requires all cabin lights on bright at all times during turnaround to "charge it up" so to speak. Its useful in that in the event of the cabin breaking up, at least the Photoluminescent lighting doesnt require power for it to work - so there is no wires etc needed for it to work - whereas with normal LED type bulbs they require power (which comes from a separate battery) and therefore all wires must be intact.
