Ok, I got all the bulbs off my old SiR before it got dragged away to the scrappy and I am sure that I have the boxes and numbers for them at home so I shall see if I can get them and the recepits too and go from there.
I don't have the URL's here with me at work right now so I am hoping I saved them on my home PC so I shall have a look later and give you all a list of the stuff that I got.
I got this URL for a raybrig bulb:
http://store.racinglab.com/rayrevligbul1.html
Im sure the Aux bulbs I had are PIAA's and I think these are the ones:

Didn't buy them frmo here though so I need to find the UK based site for you guys. The Aux bulbs need to be single filiment bulbs (you can use one of the rear brake lights if you wanted).
Will have a look later...
