Interesting! Thanks for the tip, Ill try that in the meantime. Funny thing is that when replacing the bulb with a new one the problem went away for about a week then returned.
Its so very dim that I worry about other drivers not seeing me signal.
EDIT: I installed a used OEM wiring harness for my lights, this solved my issue, interestingly the harness had a detachable socket for the turn signal rather than being hardwired, might this be due to a mid generation update?
