If that is the case, then there are two scenarios:

1: Your HID kit is defective.

2: Go back and check your work. Verify that all your electrical connections are tight. Verify that you did not accidentally disconnect or forget to reconnect any other electrical connections. Verify you didn't break anything while doing the install. Try temporarily disconnecting the HID kit and replace the stock lamps and see if it still does it.

I'm not trying to sound like a jerk, but there's only so much than can go wrong when replacing a headlight. Start from a known configuration (stock) and work your way outward until the problem reappears.
