Umm as far as i know we get the same Cultus as in thailand or maylasia. I talked to some guy on some forum.
You do need to check if the headlight it self has motor behind it. Like the spot where the bulb fits is there a motor and a plug to connect to. If there is then its 100% possible . as the person in the forum had the motor he just bought the switch and did the wiring.
Switch can be bought from bilal Jung of any 660cc japanese car but you'll have to alter it to make if fit or buy a proper one for cultus from Ali express
and you'll need to do the wiring too. No idea about that
