HID - High Intensity Discharge Xenon lights are like Lays Potato chips?or was it Pringles?anyway, once you have them, you can't go back?once you pop, you can't stop. You want?no?you need them badly.

True HID lighting is an expensive proposition. There are high power replacement bulbs with a smsall amount of Xenon that get you to about 70-80% of the HID experience. Expect to pay $20-40 for a pair of replacement bulbs. Installation couldn't be any easier?it takes about 6 minutes to replace both bulbs.

Here are the different projections (OEM on Right...bright white on left)

Sylvania makes a great ultra white light.

With that said, if you can afford the STi HID lighting set-up?go for it! Not only do you get the HID driving experience, the STi HID lights are a hundred times better looking than the standard WRX setup.
