Just wondering about the power flip up headlights in some cars.
How does the motor know when to stop when it's fully opened or closed? is there a mechanism/relay thing in headlight assmebly attached to the motor, or inside the car?

I'm guessin there has to be at least 3 (maybe 4) wires going to the motor,
so that when u apply power (the 1st positive wire is connecetd) the motor opens and when u turn off power (the 2nd positive power wires is connected) the motor closes?

I'm thinking about using this in a custom project (non lexus), but need to understand the wiring, switching behind it

thanks
Ken
