The bulbs will be the same size in all the corner lamp assemblies. You will probably want to upgrade the bulbs, especially if you go for euro clears. it is up to you and your taste. I paid $18 for a set of PIAA xtremewhite bulbs for my corners. I like them, but the blue film can get you a ticket if the cop is a dick. Maybe some others can update you and I on the prices for these bulbs.
Later!
