Motorcycle Repair: turn signal light stuck on, filament bulbs, double filament

Question
I recently got a v star 650.  I have had the bike for a couple months and no problems.  On my way to work I noticed the reaf right tail light and the front left tail light are not working. Also the left turn signal indicator/switch will not work.  Funny thing is that all these problems seemed to happen at the same time. I can only guees that this is a electrical/fuse problem.  My bike has led rear turn signals. Any help would be greatly appreciated.

Answer
Grant, I am not familiar with Yamaha electrics. In the past, they used all kinds of relays and modules to control lighting, so it is hard to troubleshoot w/o a manual.

What I would start with is to remove all the bulbs, inspect the sockets/bulbs and the ground connections for each light assembly.

The front running lights have double filament bulbs, so the running lights stay on when the turn signals come one, for each side.

The rear turn signals should have single filament bulbs and the tail light will probably have a pair of double filament bulbs.

Test the bulbs off the bike, to ensure that each one is working properly. LED rear t/s bulbs may or may not affect the flasher system on that bike.
