A word of advice on hid kits, the cheap hid kits might fog up the headlight lens from the inside, this is caused by UV rays which the hid bulbs emit.
It wont happen overnight, but slowly over a period of time you might start to notice foggy spots on the lens, which will get bigger over time.
I recommend to buy hid kits with better quality Quartz glass UV filtering hid bulbs, such as this kit:
