Not really.  Back in the day my mom learned to use a slide rule when working in a factory.  If it's part of the job you do every day it's no big deal for someone to learn that three short and two long means the digit 3.  

Geeze!  Look at all the damn blinking lights in use today.  PCs used to beep codes for boot errors.  Even devices with hugely complex interfaces will have blinking lights with very specific meanings depending on just what they are doing.  Even my Tesla uses a tiny icon with a red light to indicate the media for storing video is ready.  Then there are several other states I don't remember because I don't see them on a regular basis. 

Something like this a person sees every day will be second nature after a bit.  

Actually the best idea is to print a label with the count, but I assume there is a reason why that isn't being done as it is a rather simple and obvious solution.
