Does anyone have any idea when the brake lights come on when you are using one pedal driving.
I’ve been trying to get someone to follow be so I can find out, but so far no luck.

I don't have a Lightning yet. This does define one of the most frustrating things about driving ID.4. I hate following traffic thinking I'm a nervous douche brake checking everybody when I lift off the pedal. I don't want to be plowed into, either. There are defined parameters using the vehicle's decelerometer, but they are hard to figure out without knowing when the brake lights are triggered. Makes me wish for those weird fiber optic light indicators on cars in the 80s. A tiny brake light display in the cluster would be great.

I will test later today but almost all EVs with one pedal will have the brake lights come on when you lift off the accelerator all the way. Our Ioniq 5 does as I tested that when following my wife a few weeks back. With its 4+ regen levels, the brake lights come on in Level 3 or higher but not in Level 1 or 2.

The one pedal in the Lightning is stronger/quicker regen than the Hyundai but still smooth. I'd say that overall Hyundai's I-Pedal is better tuned. I do use it on the Lightning when driving in true city conditions but not in the outer burbs where I live.

It does turn on. Though the instrument cluster doesn't show it (would have been a cool addition including vehicles it detects around it; like on a Tesla/Rivian)

Still waiting for the Ford, but on my Model S and Model Y, I can see when the break lights turn on in the car visualization on the screen. The break lights will not come on when you only slightly lift your foot off the accelerator, but will come on when your speed decreases from 70 to under 65, for example. But not from 70 to 68, 67 approximately. I’m also curious how it will work on the Ford.

Very good question.

Ford uses an accelerometer in addition to the brake pedal to determine when to activate the brake lights. I have had my wife drive behind me and talking with me on the phone when I was driving the Mustang Mach E in 1PD. She reported the brake lights coming on exactly when I thought they should. It is based on the rate of slowing by the car, so a very gentle deceleration/regeneration doesn't light the brakes but backing off the accelerator enough to feel a significant slowing does. You definitely see brake lights any time you let off the accelerator completely.
