I know a buddy of mine in Thailand said he melted the stock reflector on one of the first gen QingQi200 bikes when he swapped out the bulb. I believe he put a round DR200 reflector in with an HID kit to solve the problem.

Regarding the wiring, sounds like the best thing do do would be to ground the lights directly to the frame and run relay switched power from the battery. Stick some automotive harnesses in there and that should solve just about anything as long as the reflectors don't melt.
