Dear Manzerick,
Look at the XeVision website
http://www.xevision.com/ and you will find a variety of HID lights for automotive applications, both round and rectangular. They offer pencil beams, driving lights and fog patterns. After you have decided on a model, give them a call to define your individual needs:

I hope this has been of some value. I don't know if there are other companies in this line of work, but the XeVision portable lights are very popular on this Forum, and Dan has been most informative about the engineering of their products.
I am looking at their HID lights for my car right now. I just need to find a place to mount a pair of driving lamps, as they are more efficient than incandescent bulbs of similar power consumption.
Enjoy,
Harvey K.
