I play almost no lead guitar, so I'm probably going to get some theory/terminology wrong; bear with me:

You play a scale on, say, the first fret and want to use the same fingering further up the fretboard; the dots help to become oriented quicker. Source (sorta): Article I read on Roger (Heart) Fisher back in pioneer days; he had LEDs put in his fretboard (I believe on the side) so he could find his fingering in the dark and/or during an on-stage light show.

Feel free to clean this up.
