I think the 'headlight/lights on during lock or unlock' only occurs when the auto-on sensor recognizes that its 'dark' and doesn't flash the lights, etc. when its 'light' outside. I seem to recall that in my garage they always flash unless the angle of the sun is just right and outside during daylight no flashing. I've got the regular comfort package and not with alarm but don't think it makes any difference. The only way to avoid the flash (w/o splicing, etc.) would be to turn the light switch to off (although I haven't tried this myself). I also own a Mazda3 with factory HID's and the lock/unlock just turns on the side and tail lights, although the auto-headlights aren't quite as sensitive as the smart's. The smart's seem to change with a passing cloud so regardless of the lock/unlock that may also make them wear out prematurely as well
