-x-, not sure if you can or not. But if your looking simply for a bulb that is alot brighter and wont melt the lense or assembly you might try the piaa w2, part number 19224, it works really well with the sylvania silverstar's I have in mine. The w2 has a little hint of blue, but they match the silverstar's really well compared to the dull orangish/yellow stock bulbs. Its pretty simple to replace the bulb, although you do have to have medium to small sized hands to do it without taking the front cladding off. This ofcourse wont get you your fogs, but I was just going for bulbs that actually looked good compared to stock.
