I didn't even notice mine until I was in the house and looking outside.Same thing happened to me on Sunday. I had the hood open doing the wiring on my ARB twin compressor install and the light show was going. No horn beep or anything like an alarm; just the lights flashing in sequence. I just locked (or unlocked...can't remember which) the jeep from the key fob and it stopped. I only knew what it was because I read your post about it that morning.
