Hey,
LED headlights are nice but swapping halogen headlights to LED headlights in a Nissan Kicks isn't a great choice. It would require more room, and you would need a conversation kit (I believe non are made for the Nissan Kicks.) It isn't impossible, but the amount of work, time, and possibly money needed to do a custom swap may not make it worthwhile. I would recommend investing in some fancy halogen bulbs rather than going through the struggle to convert to LED. But, it's your choice.
Good Luck.
