had the same problems with mine i baught them from procarparts.com and in certain spots i have a gap but i think its how you cut it out and it doesnt look bad another thing is i baught the OEM headlight switch w/fog (07 si) and fog light harness for the interier and its awsome got hids in them ***** too
the harness that came with them didnt match up at all no instructions either and when i called procarparts they were like those are the fogs for your car lol
