I think after I looked for a while it was either fork out quite a lot for a clean set which could be:
standard UK set with tango inserts
modified UK set that have been detangoed
standard UK spec C set that come detangoed from factory
JDM HID set but would need to add on washers etc.
Or refurbish your original set either yourself or send off/take to garage that offer this and replace the bulbs with LEDs
I am sure @asperformance will see you right, that is where I will be headed once my bulbs go pop
