green is "open"
red/lock is "locked"

everything in between is on a scale, just because the orange light is on doesn't mean its exactly 75% etc, and just because a certain light is lit up doesn't mean its exactly the same setting you had it on last.

basically the more you scroll it forward, the more the centre diff will bind. full rear is tailiest (35:65 split) full front is 4WD (50:50 lock)
