im gonna see if we can do a group buy, i want another set for lisa mk4, so ill email some companys over the weekend, and see whats what, if you want the dip and main beam you need the bi-xenon h4 kits, they have dip and main beam in one bulb with a switching relay.. other get the normal h4 kit, but lose your main beam, which tbh, aint a bother as they are so bright. ill do a fitting guide, when bens round mine in a few weeks..
