Does it work if you turn the 4 way flashers on?

You could try to unplug the connector and reseat it. Beyond that, I would take it to the dealer

 

[XLTJOE]

Unfortunately no , it works only when I apply brake
4 way flasher Orange bulbs working perfectly fine

I would keep a close eye on it. If you take it in while it's working I would guess they can't fix it because they can't duplicate the issue. And if it happens again take it in ASAP. Even if they can't work on it then they can see that it is an issue. Good luck with it.

Tail and brake lights are LEDs, turn signal and flasher are incandescent. If the brake lights work and the tails don't, it could be a flakey connector. That seems unlikely, but possible.

My ST is at the dealership right now for the left tail lamp to be replaced. Right tail lamp is fine. Getting the recall work done at the same time along with the driver’s seat side panel.

So my dealership claims that Ford is denying the warranty claim because I don’t have “Ford bulbs” for my turn signal and reverse bulbs. I guess they don’t know about the Magnuson-Moss Act.

That is something that can happen with certain mods. From what I read about that 'Act' there are some exceptions to warranty coverage.

The tail lamp is an LED panel. Please tell me how a non Ford bulb would make an LED panel stop working when the non Ford bulb isn’t connected to the LED panel.

 

[peterk9]

If the above is direct at me then I don't have an answer. It would be better off directed to Ford.

[Ronxlt]

Well you did respond to me, Peter. So, it was directed at you.

 

[Ronxlt]

Update on the dealership. The mechanic, service advisor, and service manager all thought that my LED turn signal had been spliced into the tail lamp wiring. It was just a plug in bulb. I went to the dealership and unplugged it for them and put the Ford bulb in. They looked very confused. So after all of that the tail lamp is being replaced under warranty.

It's not the first time an owner has had to do the work to get things done. Good to hear about the warranty coverage Ron.
