Pulled my bike back in the garage after a short ride.Put it up on the rear stand and for some reason the bike tipped over on the right side. I WAS PISSED! Picked the bike up and saw that the mirror was broken and a scratch in the rear cowel sticker. Not to bad, I had an extra set of mirrors and I'll get the sticker fixed. Now my rear brake light won't work when I press the pedal. It's not bent and the light works when the front is pulled. What happened and how can I fix it?
