What triggers an observer?
An observer is a block that emits a redstone signal when the block or fluid it faces experiences a change.
How do you make an observer detect a player?
Observers cannot detect players or other entities directly. They can only detect block changes. You could have a pressure plate at the bottom which a player must step on to enter the elevator. Use that signal to start a timer that will turn on a lamp for the estimated time that the player will take to ascend.
