Problem with HID lights

I finally got round to buying a set of HID lights the other day as been missing my xenons since i bought the car!

Took the bumper off last night plugged them all in and nothing?

Thought it all looked to easy to be true.

Followed all the instructions, everything is plugged in fine and how it should be but there is no life. Sidelights work but main beam is dead.

Checked the car over and all the fuses just in case but there all fine, and plugged the original bulbs back in and they work as normal.

Im using this kit here.

I will get a picture later of the wiring but basically it all loops from bulb to ballast and then two spades plug into the loom off the light.

Any one came across a problem like this before?

Thinking maybe i have a faulty set?
 
I replied to your PM but just wanted to add, check the two spades on the loom are the correct way around (i.e positive to positive and negative to negative)
