I have a new 2009 M1100, and when I turn the key off, I have two blinking red lights above my instruments, kind of like an alarm system. This is nice, but I don't have an alarm installed. What are these lights for? A scare tactic?
my 2002 750 has a blinking yellow light, i always assumed it was for the steering lock [shrug]
My S2R has a yellow light - it's to show off the immobilizer. Stops flashing after 24hrs.
Don't know if this is what you see on your 1100, but I would guess so?
It is the immobilizer, and like stopintime said, it will continue for 24hr after you turn off the bike.
