FOB, 2002 x type

Have a new FOB for key, my old one did not work.
Question I have is what is the function of the red left side
showing a headlight?
x-type 2002 3.0

Probably lights the headlights so that you can locate the car at night in a car park?

When you press the button, it lights up the high beams for a timed period, so you can find your way to the door, ect.

I was’nt sure, and do not wish to just push buttons.
