personally, i thyink the white corner light and sidemarker look is cheesy. If you want white bulbs becuase the amber looks bad in the housing, there are special bulbs that are tinted gray but flash amber. You can also use a light coat of spray paint on amber bulbs.
If you really want the white bulbs, go to autozone or pepboys and look in the ricer section. The sales associate can direct you from there.
