The | represents 1 mph
The . represents 0 mph

So if it's like this :

------------------------
| | | | | . . . . . 5 MPH
------------------------

Then it's a speedo that can display a max of 10mph, and it's currently showing speed of 5MPH

My speedo displays a max of 160mph

And as you can see from the Screenshot, I have 47 | and 113 .

If the speed is 170MPH, then all the . turn to |, but it will say 170MPH, So no need to worry about it bugging when you go above 160MPH
