Inspired by circuitkev00 I decided to retro fit my headlights with Hella Bi-Halogen 120mm modules.
I didn't make my brackets half as nice as he did. The nice thing about the bi-halogens is that they have a shutter to create the cut-off for low beam and when you apply power to the shutter motor it lifts up and creates the high beam.
I removed the H9 halogens and replaced them with HID H9 55w bulbs.

 

I would try to make a surround that fills up the space. Otherwise it kind of looks wierd.
