Same here... got the complete $87 kit (reflectors/bulbs/wiring) that includes reflectors made to fit the H4 type Halogen bulb that comes with the kit; they are focused and nice and bright. (I have the 12 volt kit.)
I bought the Classic Vintage 6 volt halogen bulbs last month and installed them along with the new Bratton's aluminized reflectors. The bulbs focus perfectly and they are extremely bright.
