Where does the headlight power come from?

If you are to believe the icons, the 12V 50A circuit feeds the heat pump in BEV, so there is at least 1KW capacity in the 12V system.
The 3KW resistive heater in REX is apparently fed by the High Voltage battery.

600 watts
but with all the other stuff i geuss up to 1000watt is what to expect.

I checked a BMW document, I was wrong, the heat pump works off the high voltage battery. They don't say the 12V system capacity, but considering the number of circuits on it, including the rear glass and seat heaters, power steering, lights, etc., 1KW is a good, if not a conservative estimate.
