The first thing I think of when a light goes on is, Oh it's brighter now.

Damn-it turn that thing down you trying to blind me! (my first thought)

Maybe the light of knowledge should of never been turned on.

Or turned up in slow steady increments so as not to cause the above to happen. (a rheostat works wonders, it lets us adjust slowly, or blindingly fast)

Can we turn on the lights of society. Make a bulb shine so bright it is the bulb everyone will see.

Oh yes see the Damn-it line, society has been blinded and we the people did it. (get ten 10 year olds, ten 30 year olds and ten 60 year olds, they are the government for 5 years, then start again.) Why those ages you say? They are the age of the stubborn. No one can tell them what to think, so any consensus rules they come up with are going to be good rules.

Do we want someone to turn the light on?

Only if they are a tribunal as mentioned above, otherwise leave the lights off, and let people light their own way through the dark, I am tired of society, (other people), telling me what direction I am allowed to travel.

Will one more light in a world of bulbs make any difference.

Not if the light is lost in the overglow of all the other lights. If the light stands alone and above the rest, and can cast it's glow toward those seeking a different path, then one more bulb might make a difference to at least a few that can see it's glow.
