Hi Mate, theyre not too hard, its a case of wiring up the ballast boxes to the original wiring and simply fitting the H7 bulbs in. Unfortunately its a bumper-off job!
Inside the lenses there are metal shields. Some HID kits have the bulbs very slightly too long so you have to put your finger in and GENTLY push them out to make them convex in shape.
I see your in Chesterfield! Theres plenty of us from around there, if you can provide bacon sarnies, im sure some of us could pop over for a hand (weve done it about 3 times lol)
