lol... what a way to figure out you got a headlight out...
don't worry man, i had "WTF?? Why's it so dark??" happen to me when my brights went out. I always leave them on, they burned out, so I was cruising around town with just those tiny little bulbs on the side on for a while...
P.S. For any of the fellow SV'ers here... do you know if the brights can "burn out" but the low beams still work? That's my case... I checked the fuses already and they were fine... not too handy with electrical work, but I gave it a professional jiggle at the control switch/left hand grip - nothing.
