So I bought this cheap nasty headlight off trademe:

And I want to make it legal.

Problem is, the bulbs are $6 sealed halogen houselights. Tried just covering the top half of one of them (idea to run one higher wattage bulb at a time) but seemed to be no good, houselight halogens seem to bounce the light everywhere before it finally goes out front, will try another couple crescent moon shapes though, see what happens.

But just in case there's someone else out there with a cunning idea for this, please do tell, and if someone else has played with these, what did you do?
