We built a handheld device with only a few LEDs as a UI and found that people can easily tell solid from blinking and they can count groups of blinks up to maybe 3 or 4. Using blinking frequency did not work out well at all.
The WiFi LED was blue and there were lots of coverage problems at the customer sites . We wrote a blues song "The Blinking Blues" about it and performed it at our offsite. One of the lines was something like "I don't know if it's blinking fast or slow."

Is this the case even with a large difference between fast and slow? I would imagine that there's a large intuitive difference between 1 Hz and 5 Hz, for example.
