Notes:
Replies is ‘Can Messages’.
Timeout is for all messages, not per message. If replies is
set, the 0xFF will be returned after either a) the desired
number of replies is received or b) this time is reached.
Timeout cannot be 0. If a zero is submitted, a value of 1
is used instead.

Notes:
Because we have conditioned the user to expect the vehicle
light to light or blink, you might want to follow the same
model. You may also find this useful for debugging.
