Is power available to the low beam side of the bulb? Could the bulb itself be whack?
WOW...just freaking WOW!!! What are the odds of having 2 bad bulbs?
I bought a new H4 bulb, and it worked !!! Slap my ass and call me Sally!!!
The bulb I had in the bike was maybe a year old and was working. The replacement bulb I had was working when I last used it. Both show no, I mean zero signs of being burnt out, i.e. all filaments etc. *are solid/attached*, no discoloration, no noise when shook They both look *perfectly fine*!
Slipped the new bulb in...low beam works. Went deep into my spare bulb stash in my emerg travel kit, and that works as well.
Wow, lesson learned I guess. Even if you have 2 bulbs that look good, and the low beam doesn't work on either, try a new third!!!
At least I now have a refurbished switch. lol...(and a used spare on the way :-) )
Live and learn.
Thanks for all the feedback.
