I would really like to upgrade my mom's Prius headlights to projectors this Christmas. It is a 2008 Prius with factory HIDs in reflectors. The beam pattern is not terrible, but I think that a projector would make her much more comfortable.
The only "plug and play" Prius projectors are for H11 bulbs - and I do not want to upgrade unless I can use the Philips lights that are installed now. Is there any sort of adapter or bracket that will let a D4S bulb to work in a projector designed for an H11?
This is the headlight I am looking at getting for her - http://www.carid.com/2008-toyota-prius-headlights/cg-ccfl-halo-headlights-313181.html (but I am getting them from eBay - I just don't want to link to eBay).
