One of my rear running lights in the blinker pod suddenly stopped working on my 2011 Street Bob. The blinker and brake light function both work but the I have no running light. I haven't done anything new or changed anything this year so I am kind of stumped. I replaced the bulb already thinking it was a bad bulb but that didn't solve the issue. Wondering where to begin in getting to the bottom of this? Thanks for any help! Set up shown below.
