Projectors

I had a small questions about the projectors, I know that with the factory headlights its not good to use high and low at the same time but what about the projectors, they use two bulbs so the heat shouldnt be a problem.

Heat won't be problem. There are other potential problems if you are powering the dual bulb lights through the factory harness. The stock headlight plugs are not up to the task for continuous use. The stock circuiting of the multifunction switch may not withstand the additional current. Running the high or lows (or both) through relays and taking the load off of the multifunction switch will eliminate those issues.

I recently installed projectors in my '00. I put an HID system in the low beams, but the halogen bulb setup would be done the same way. I made a small change in the multifunction switch wiring harness to keep the low beams on when you move the stalk to select high beams. It is covered in this thread, starting around post #4.
