Hi, Just wanted to confirm which size canbus I require as I was told it was 39mm, but when I did a search on ebay some show as 36mm.

Does it make any difference if it has 3 led or 6 or whatever?

Im looking at something like this - AUDI A3 A4 A6 A8 CANBUS LED NUMBER PLATE BULBS PAIR SV8 C5W 239 257 269 272 Q7 | eBay

This will replace the rear license plate, but am I right to say that I can change these in the interior lights and the boot light in my C6?

Please correct me if I am ordering the wrong one as now it is getting darker having a brighter boot light helps alot.

Thanks in advance.
