I've had the dome light switch turned off for years, as they are parked in my garage, and I got used to leaving the door unlatched, or even the back open for loading / unloading.  One of mine had a flaky dome light switch, so I always had it shut off.  I just got used to that, not worrying about closing the door at home.   
	Well, when I typically drove one or the other [I have 2] every other day, the 160mA isn't noticeable, unless you measure with a DVM.    Anyway, with the current situation, I've been driving once a week, maybe twice.  So I go out the other day, turn the key, and NOTHING happens, not even a click.
