I thought any stock car that does not come with the HID/white
lamp is considered illegally mod. if you replaced it yourself. Few
weeks ago, the TP conducted a night exercise and fine many car
owners becos of this (publish on newspaper).
The reason TP gave is too much heat generated and may lead to fire,
also block vision of other drivers due to the brighness unless the
car comes with the auto adjustment control (standard in higher
class Merc., BMW, Lexus i think) for the lamp angle. However, if
your lancer comes with a manual control one, then maybe you can
install the white bulbs and just lower the front headlights to
point more towards the ground.. else not recommended unless you do
not mind "donating" money to TP
