Just picked up 2 sets of these for less than $30 shipped to the door. They're small, but they are BRIGHT and throw a nice, tight pattern. Hella's site shows them as having a 500 meter range. 
I found 'em on Ebay using this search Look for the text "NEW $225 Hella FF50 German Made Fog Lights NR" in the search results. They're usually listed 3 times in a row, and the seller lists 3 sets every day, starting at 99 cents. They're some kind of liquidation store, so no telling how many sets they have left.
Even though the title says Fog Lights, the part number, 74320, is for the driving light version. The lens is clear and the reflector is designed to direct the light pattern. These are every bit as bright as the big Hella 500's that I have on the family truckster.
You get the lights, a pre-terminated wiring harness, a switch, and a sweet relay with a built-in fuse holder.

"Hmmm, this do-hicky from this what-ya-call-it would work perfect for a some-gadget on a K5"
