The running lights use the headlight fuse. The left and right signals share their own separate fuse.

Did youopen the handlebar switch box recently? Did the bike get really heavily wet recently?
Although it would be odd to lose both the front and rear signal bulbs twice, check them again anyway. When signaling left, and when signaling right, does the tach signal indicator illuminate and flash even if the right-side bulbs don't?
Theright-signal power wire would have to be completely brokenafter the handlebar switch but before theflasher, while at the same timenot shorting out,for the fuse to remain intact AND for the front/back/tach indicator to NOT illuminate on justone side (left or right), so its not likely a wiring problem - so lets skip that for now.
If the bulbs are okay, the problem is most likely either with the (1) flasher, or (2) handlebar switch. Check your battery box (in the relay well on the right side) for water in the bottom, causing a short. The flasher lives on the bottom.
I believe the yellow/red wire exiting the handlebar switch goes to the relay-right signal, and it exits the flasher as the dark green wire we're familiar with at the bulbs.
Let us know if this doesn't resolve it, we can take the next step.
