You will need a relay and they will need to take a feed from the main beam circuit to switch them so they only operate when main beam is operating. To be honest though the spot lamps will be designed to work with a halogen bulb not a HID bulb and as HID's take some time to come up to operating output their use here isn't very clever. This is why many HID equipped cars only use them on dipped beam and retain a halogen bulb for main beam.

To be blunt, I think you've boobed
