Both Blinkers blink when i turn on a turn signal

[Full Throttle]

Okay so i was riding home last night and my buddy was following me in his car. Well when we got home he said that when i turned my blinker on that both of them turned on. I did some investigating and discovered he was correct. However if i turn lets say the left blinker on then its on and really bright. Now the right one turns on as well but is very very dim. But they are LED's so at night even a dim LED looks pretty bright. I checked the wiring and looked followed it all along its path and it doesnt intersect with anything or touch anywhere none of the wiring is corroded or cut. IM kind of stumped on why its doing this. Anyone have an idea or a solution?
