highbeam not working

Ok, highbeam was working fine yesterday, and this morning after my ride into work, I was switching back to highbeam as the bike was still running because I ride with it on during the day, and both of the highbeams are not working. I check the voltage, and thet battery reads 13.6 or so when the bike is off, and up to a fairly steady max of ~14.25 when the bike is idling, and about ~14.16 when I bring the revs up. I checked the 20A headlight fuse, and of course it is ok (It would have to be I guess since the lowbeams work).

Anybody have any ideas? I am curious why "both" highbeams are gone at the same time. Is it possible a voltage spike killed them? Could it be the switch it itself? My bike has around 32,000 miles on it, and i doubt the headlights have been changed before as they usually last awhile. Oh, and my R/R was upgraded to the larger one before that I bought it. Any ideas would be appreciated.

 

I can see at least one damaged/burnt filament....now I am just wonder if it was just a coincidence that "both" highbeams went out at once, or maybe I just never noticed that I only had one highbeam on? I don't think so, because I am used to seeing my reflection on the back of a car, and checking the headlights.....I just don't feel great about replacing them if if they are just going to blow again. Also, why would just the highbeams blow if it was a surge....because I was using them at the time??

Oh, and I use my highbeams for 99% of my daytime riding, which is most of my riding, except for the early morning to work.

 

Thanks for the tips Action. I appreciate it. Do you have any rough idea of what voltage I should be looking for at the socket?
