Since you have a 2019, I doubt you'll have any issues. I was told that out of the 195 units Diode Dynamics has sold, I was the only reported issue. Maybe the 2021s have a slight variance in the electrical system; maybe it's just my car being finicky. I'm not really sure. I was just interested to see if anyone else has installed them on 2021.
If I was you, I would ask for another set to try. I doubt Ford resigned the lighting system for 2020-2021?. The Canbus circuitry in the lights to prevent the hyper flash must be inop. Good luck
Then your year Ford must have changed the frequency modulation of the circuit. DD needs to get a 2021 and connect a Oscilloscope or equivalent into the turn signal circuitry and mod their new light circuitry to prevent the hyper flash on your year model. They need to fix it.
Did they make it to where you could turn your interior lights off with the doors open? Did they happen to make changes to where you could adjust the absolutely Load Back Up Proximity Beeps when Backing out of the garage?
how do you stop the double horn honk when exiting with engine running? I hate that feature on my 21.
You can enable dark mode. Did not mess with the sensors. My garage is narrow so if they keep me from hitting the frame, so be it.
Have to use forscan.
We are reviewing this now, and we will definitely be providing a solution as soon as possible! There's probably just some small electrical changes needed to the circuitry to accommodate the 2021 specifically. We do back our products fully, and will continue to do so. Thanks!
