Hi mate, stick up some pics of the rear of the headlights, if you have a Uk car then you should have Hid's which mean the grey connector for the wiring will have 8 pins on it, your halogen set will not have the automatic height adjuster that the Uk ones have so the grey wiring connector will only have 6 pins.
it is possible to strip the wires from the connectors and swap them over, and this should solve your problem , once the lights are off the car swapping the wiring should only take 10 mins
hope this helps and if you have any more questions fire away
Paul
