I took my bike (an '04) and participated in a bike safety class (which involved a lot of idling). About 3/4 of the way through my brake lights stopped working with either hand or foot brake. I checked the fuse and it looked okay, but I thought I'd stop on the way home and buy some new fuses just to be sure. I replaced all fuses (except for the two big ones at the bottom). Still no brake lights. Any suggestions? Where might the relay switches be located? Thanks for any help you can give me.
