'Have lighted' is unusual phrasing. In contemporary English, we'd be more likely to say 'have lit'.
And as with 'creeps in', we get a particular da DUM heartbeat-type rhythm.
With 'creeps in', this sounds like 'creeps IN'.
With 'have lighted' this sounds like 'have LIGHTed'—with '-ed' sound marking the first beat of the next da DUM: 'have LIGHT-ed FOOLS'.
Arguably that's one reason why Shakespeare chose 'lighted' over 'lit'—to get this rhythm. (Plus 'light' it is a central image throughout the play and 'lit' is just not as evocative a word.)
Again, we'll come back to this rhythm business later in this lesson.
