i am with mulder hids in a stock unit that has a dual fitament is not a good idea. i would suggest start of with some aftermarket lights, ie uk300's, morettes, or the like...NOT THE EBAY DUAL BEAMS. if that doesnt help you, then install some HID's into those. as for the fogs, yeah get some yellow bulbs. i would suggest hella yellowstars. you could replace the stock fogs with some hella 500's or the like, AND install yellow bulbs. the thing that sucks is that i always have thought the 02's have the worst lighting output of the impreza models. although that may explain why there are SO MANY aftermarket lights for them.
