If you have the headlight switch set to "off", then you have no reason to touch it unless you want your headlights on.
If you have the headlights switched on, there's still no need to touch the switch, because they'll turn themselves off as soon as you remove the key. That is, unless you switch them on after removing the key.
Thanks for confirming. Although I thought that leaving the switch to the headlight position causes the backlight for the instrument panel to remain on even after turning off the engine and removing the key. But I will check it again tomorrow.
