Just as an update have fitted these to mine and worked out how to wire them so both lights come on together, wiring diagram here: https://dl.dropboxusercontent.com/u/79781230/HID%20Wiring%20with%20switch.jpg
Anyone has any experience with these ones? They seem pretty cheap, so I'm wondering if they are any good. https://www.ebay.co.uk/itm/White-An...033315?hash=item2a9b69df23:g:w8wAAOSwjyhaTJrx
The ones I fitted were KT (King Technology - Item No.232166691778) which seemed to feature on YT above most others. Also from China and I had to pay the import duty, add about £20 to the price for that. The pre-assembled light units save you the trouble of opening your own. However, that part is not too difficult and, once open, the projectors are then a very straightforward fit. You will still have to find the space for the ballasts, relay pack etc. and sort the wiring accordingly. Keep posting if you go with either option and fit them.
The only concert for me with these ones from china, is that I have no idea what the actual lights would look like. They say it's not DOT approved and for off-road use only, so I'm a bit hesitant if I will be blinding people on the road. Also don't really want to open my headlight unit, would rather have something to backup on if it goes south
I fitted the kit to a spare headlight unit (eBay is your friend) so had no pressure to do the conversion quickly, could cut it to make room for the ballasts etc. the lenses are CE marked and I still have the original to swap back if necessary. Hope that's helpful Bud.
The xenons stopped firing up and MoT is imminent... have to put the original light unit back in* while I fix the switching unit. The relay circuit has got damp and corroded the main power connections inside... relay still seems to be working (can hear the solenoid) but the soldered joints have suffered... * see post by @Stuish: https://www.1000rr.co.uk/threads/new-mot-rules-headlights.40631/ ... so probably would need to swap units anyway
