Right blinker flashing really fast Left normal
I just picked up a 2018 F-150 XLT Super Crew. 49K miles. As I was coming home with it I noted that the left turn signal blinks normal speed, but the Right one blinks like it has a burnt out bulb. I checked and all 4 lights front and back are all forking as they should.?? Now what

Welcome to FTE BBQ Phil,
Just a guess, but it's a place to start looking. Someone probably replaced a burnt out bulb with a LED. The LED bulb doesn't have the near as much resistance as regular bulbs, so it will still give you the fast signal sound error, even though it looks like it's working fine.

I just bought a used 2019 F150 with 14,562 miles just last Saturday, when I test drove it everything worked perfectly. On a 200 mile trip my left turn signal indicator flashes fast like a burnt out bulb. Both front and rear left turn signal lights are blinking correctly when checked. I guess it is a warning that one of my bulb's in getting ready to burn out. I'll will replace the rear bulbs1st.
