why do you want to install HIDs in the first place? more light? just fit a decent set of bulbs (the best you can find) and get your lenses cleaned. the baleno (in all models) has very good light from the original headlights when they are new. it's possible that your lenses are dirty from the inside and could benefit from a good cleaning.
remember, HID's are technically for offroad use only because htey do not conform to street use standards.
movies and games have made HIDs into a craze.
However if you are planning on fitting HIDs to your car regardless, then i'd suggest that after installation you park your car 5 feet (at least) from a wall and adjust your headlights down a little as usually after fitting HIDs the light patern us too far up and blinds oncoming traffic.
Avoid projectors as they may look good but actually have no benefit over the stock lamp (in most aftermarket cases)
