Digits only go from 0-9. However, you can't just not flash in order to represent a 0, so the numbers are all off by 1. In other words:
1 flash = 0
2 flashes = 1
3 flashes = 2
Therefore, you get this:
The coordinate system only accepts input with one decimal point, with each coordinate being less than 200. The logical division of the numbers is therefor: 151.7, 174.4.
Enter those coordinates and claim DaisyDisk as a prize.
