Since it seems to be occurring in the headlight plus the right side, I'd guess you might have a burned out flasher unit. You can replace for ~$10 at any auto parts store.
Or, it could be a loose connection in the headlight harness or somewhere in the middle that just needs to be plugged in again.
It's tempting to think it could be a fuse, but as far as I know none of the fused circuits are dedicated to a particular side.
What the bike's history? Are you the original owner? If not, do you know whether the previous owner(s) meddled with the electrics?
Have you tried putting in new bulbs, anyway, just to see if they work?
There are wiring diagrams in the owner's manual as well as in Snidal that can help you troubleshoot.
