Right rear light casing was slightly cracked at the top. I taped it up as a quick fix. A few weeks of winter rain lead to a fish tank in the bottom half of the light casing. I then drilled a hole in the bottom of the casing to help drain.

Once the bulb burned out the hyperflash started. Finally got around to fixing it. The bulb was shattered. The socket had some rust/corrosion. As did the connector.

Replaced the bulb. Didn't work. Replaced the socket. Didn't work. Fuses are all good. My brand new trailer's right turn/brake is not working either. All trailer fuses are good.

Ford wants $50 for the connector leading to the socket. I didn't want to get to this part unless I had to.

Wires look fine underneath the bed. I recently had to rewire my 7pin socket, don't know if I could had screwed up anything there.



Long story short. Passenger, rear, bottom brake/turn/running light will not work. The top light functions 100%, but hyper flashes when blinker activated. Right turn/brake on trailer will not work either.
