I'm having issues with my tail lights. I'm at a loss! So my when I turn on the bike the running lights work when I flip the left side blinker on at blinks at normal pace then it starts blink fast all lights work front and rear none of them turn off during all of this when I put the right one on its blinks normal pace all the time when I hit the brakes front or rear brake the left one turns off while the other one brightens like it should I switched the bulbs out and it's still the same thing I check all the wiring and the fuses look good any ideas?

 

Sounds like your left light has bad ground.
