Default Forcing LED to be on also with screen on?

At first I thought this was impossible, I am using "Light Flow" and always as soon as I unlocked the screen, the led turned off.

But now, I flashed a kernel with touch controls, and I notice that when I wake up the screen with a double tap or a swipe, and I'm on the PIN/etc locker screen, the led is still ON! In fact, it can stay on until I unlock the phone..

If hardware can handle screen and led on at the same time without a problem, there's any way to keep it ALWAYS on without caring if you wake up the phone with the button or unlock it?
