As the title says I have a 2008 f450 and I am having some problems with the passenger side blinker/ break light. I have a flatbed on it with LED lights. Nothing fancy just trailer style lights. The tail lights turn on when I turn the running lights on but the blinker and break light on the passenger side don’t work. All other lights work including the passenger side mirror and headlight blinker. I switched the passenger side tail light with the driver side to see if I just needed to replace the light itself but it still acted up. I then replaced the LED condenser on the passenger side and that didn’t work either. The next thing I did was clean and tighten all the ground wires under the bed to still no avail. I’m not much of an electrician so I am hoping I can get some ideas from y’all. Thanks in advance for your time.
