i believe d2s and 9006 share the same slot to plug in to your headlight... my intentions are to obtain some bmw/audi projectors units, pop out the ones in the halo projectors and replace them. this will offer a higher quality projection of light. but i would need to eliminate the h3/h1 setup and fit in a halogen 9006 which is cheaper than an hid d2s, anyone follow?
