bro to be very honest with you i think HID's are a waste of money and getting peoples curse.
i come across so many cars who have HID's installed in them with reflectors and i don't know what sort of curses i give to them, obviously because i lose vision of the road because of them. brother first of all it is very dangerous because the other driver in-front of you loses vision of the road. no matter even its for a second, on the road accidents happens in seconds and not minutes. one single mistake and that's it. it could cost lives.
if you think that the stock lamps do not have enough light then you can try the bulbs with higher power ratings and also there are bulbs with diamond white colour which may give you the look of hid. but please avoid getting hid's.
also i think modifying your headlights just to get HID is insanity because nothing can beat the stock settings. for cars with stock hid installed are the ones who shall keep hid's.
sorry if my post was offensive but brother that's a fact trust me.
