Yes, as soon as you hit regen your brake lights come on. I tested this with a Honda Hybrid a long time ago to make sure. If your car has a diagram somewhere that you can display while driving you will actually see it on the display.

This isn't a universal truth. It varies by vehicle, and apparently even by what level of regen is selected.

"Conclusion: Do Brake Lights Activate During Regenerative Braking? Yes, but Stay Alert"
Seems pretty obvious, the idea is that engine braking would also cause your car to slow down without lighting up the brake lights so any kind of slowdown at that level would not normally engage the brake lights. But as soon as you slow down more than that the lights will come on, making its behavior pretty close to what you'd expect from a regular car with and ICE lacking regenerative braking.
Or would you suggest that a normal car should engage it's brake lights when you let go of the accelerator and engine brake? (I can see a case for that.)
