Temporary lights / bulb?

[nidup]

"The player would see an exit strategy in advance and power them on before they pick up the crate, that way when the lights go out they have points of interest for them to go to, like leaving a trail of breadcrumbs for themselves in advance. Maybe certain lightbulbs go out faster than others, so you have to plan out the order you turn them on before the lights go out?! "

Not convinced by this one
