Headlight bulb

[oldjoe]

Thanks for the replies.  Sorry I was to cryptic.   The bike started normally, but I wasn't sure what the warning light meant, so I stopped to see, letting the side stand kill the engine when I got off.  Then with stand up, it would not crank...just dead switch, no sound.  After waiting about a minute, it started as normal.   Then I decided to turn around and go back home and a car stopped to ask if I needed help.  I shifted to neutral and dismounted to talk, but my foot inadvertently hit the shift lever as I was putting the side stand down, killing the engine.  (Yes, I do know how the safety switch works).   Then again it would not crank.   I started walking it home - 2 blocks - and the last is downhill, so I rode it - tried starter and it started up as normal (again, after about a minute wait from when it wouldn't crank).  Since I'm new to BMW, I wondered if there was something in their circuit that intentionally blocked starting off and on for light failure (I've seen stranger things).

I also recently installed new Denali D3 driving lights plus brake light and air horn - with their CanSmart controller.  No problems for several day trips after that.
 
In any case, I will replace bulb with H7 and plan on replacing the battery before next trip.  It has been on Tender since new, and has given no signs of trouble before, but it is 6 years old.
