ok you keep your original light housings and the kits are simply plug and play i will be doing a full write up in a day or two on the fitting when i have sorted out a few little niggles
for the mk5 the headlight is an H7 bulb and the kit from martyn is £327
and the light is indescribable
here is a little comparison between the phillips blue vision bulbs and the hid`s

Phillips blue vision bulb on its own (1 head light)

this is a single hid please look on the left and look at the tree then look at the above photo where you cant even see the tree!

and here the hid is on the left with a phillips bluie vision bulb on the right, the hid is very blue in this pic so depending on further testing the kits may be supplies with a different bulb that is about the same power but less blue
i was woried that with the extra light output that the bulb might produce more heat which could be an issue for the plastic lenses on the mk5 but i did a temperature test and it turns out that the hid actually runs slightly cooler even though it puts out a LOt more light please see this thread (
