Shorten Length of Tempo LED Blink

A shorter tempo LED blink would make it a lot easier to count off songs in time. Right now, it is absurdly long. At 120 BPM, it seems like the duration of the LED blink is about equal to the time that it is off, which makes it surprisingly difficult to get a tempo from the blinking LED. If you could shorten it to a tiny flash, that would make it way better. Thanks!
