Amber LED blinking scheme — The pattern is 2 or 3 blinks followed by a short pause then x number of blinks up to 7. The repeated
pattern has a long pause inserted in the middle. For example 2, 4 = 2 amber blinks followed by a short pause, and then 4 amber blinks
followed by long pause. Then, the pattern is repeated.

Amber LED blinking scheme — The pattern is 2 or 3 blinks followed by a short pause then x number of blinks up to 7. The same pattern is
repeated after a long pause. For example 3, 5 = 3 amber blinks followed by a short pause, and then 5 amber blinks followed by long pause.
Then, the pattern is repeated.
