1. it's rather hard to do. It wont pass a m.o.t (Not a legal one anyway) As the lights generally are mounted where your inidicators go. They have no light direction so it fails on that. You then have to buy switch gears and a digital speedo and the wiring on them is a total ass. You can buy all the parts from ped parts.(Exsept the lights) You use low what light bulbs for them. It's generally a bad idea on zips. My friend has one looks good but failed his m.o.t and now he's buggerd till he can get a new loom to refit his old headlight/speedo/switches. Hope this helps mate.
