I went to leave a friends house tonight and when I turned on my headlights they flickered and went out. I switched to highbeams and they came back on but nothing when I switched back to lowbeams.
I pulled the headlights and the lowbeams are burnt out.
The alternator is putting out 14.17 volts with no load and drops to 13.8 with the highbeams on. 14.17v is a little high but I wouldn't think it would blow the headlights.
Does anyone have any ideas what could cause this?

Thanks for any help!!!
