I would check that both black retaining clips are pushed down all the way, and are hooked onto the headlight. Also, check to make sure your bulbs are in all the way with the locking ring on tight and make sure you still have that o-ring on the bulb.
BTW: I was reading your mods, similar to what I'm going for with my car, just curious, have you run it in the 1/4 mile yet? Dyno'd? What are your numbers?
