I've been looking to do a retro job on headlights... and I was wondering this... why not, instead of having a projector + highbeam bulb, just have projector + projector?

I mean, have two projects in each headlight, one for lowbeam and two for highbeam, instead of a projector for low + a bulb (HID or not) for high?

Or, with a retro'd projector, would I even need a highbeam, in which I could just install a driving light in the other area of the headlight?

Also, anyone know where I could (a) get custom-fitting, high-quality halo lights, (b) where to get the parts for and how to make a custom one, or (c) will BMW ones fit?

Thanks!
