You need projector headlamps for a proper set up.
If you put a hid kit in reflector type headlamps then the beam will be all over the place.
A ballast is needed to power the bulb properly. It should sit just under the headlamp.
Or you can get xenon look bulbs which go straight in. Some examples are the mtec and nightbreakers bulbs.
Genuine vw xenons are around 500 second hand.
If you go down the route of getting aftermarket ones, expect to oay around £280 for the headlamps and hid kit.
