Visual metronomes (also suitable for deaf musicians)
From Bounce Metronome
Many metronomes have a light or something like that that comes on for each beat, but not particularly optimized for visual use.
This page is for metronomes that are designed to be especially easy to use as a purely visual metronome. It is a selection from the Big list of Windows and Online Metronomes page.
If you have any favourite visual metronome left out of this list, do let me know!
