Where is the headlight sensor?

Where is the headlight sensor? I want to stick a piece of tape over it so my headlights are automatically on full time, day and night.

Is this a trick question? Just turn the headlight switch from 'auto' (far left position) to 'on' (far right position)
Unless I misunderstand your question?

It is not a trick question. I just want headlights on whenever the car is running. I have CRS and forget to turn them on and off. My GoldWing and Dodge Diesel have lights blazing all the time, it helps other drivers to see you.

I guess if you leave the headlight switch in the 'on' position, they will be on when the key is in the 'accessories' position? So you would run the risk of flattening the battery if you were parked up listening to the radio, for example. Or do the headlights not come on unless the ignition is at the position after accessories? I've never actually checked...
My guess is that the ambient light sensor is in the same place as the rain sensor on the windscreen up by the rear view mirror? Shouldn't be hard to block off that area and see if the headlights come on.

The headlight sensor is up in the center of the window near rain sensor. You can see the eye if you look closely

If it is that important to you I guess you could remove the plastic rear view mirror cover and stick a black piece of paper over the eye.

Do the Z4's not have angel eyes? those are more noticeable during the day than low beams anyways.
