Hi, I have searched around the forum but still can't work out what I exactly need, hoping someone here knows a little about it
I want to put in some LEDs I’ve found the licence plate ones from eBay I think these are fine https://www.ebay.co.uk/itm/253514484761
And I also found this set for the interior which I think are ok https://www.ebay.co.uk/itm/142664166901 but when it came to the sidelights/citylights I saw so many that said they are for the B7 but all seemed to have different numbers next to the descriptions eg T10/W5/501 etc and I have no idea which are the right ones, also people on here were talking about error codes, needing resisters etc... Anyone tell me which ones I need for sure? (preferably from eBay or Amazon) And the same goes with Spotlight/Foglight bulbs? Btw my car is a is a 2005 and I have the Halogen headlights not the Xenons as from what I gathered from here it make a difference.

Also am I right in saying I can change these bulbs without having to remove bumper and headlights? as I had the bumper and headlights out just last week as I was spraying the headlight chrome strip and grey panel inside them and that’s the 3rd time I’ve had the front end off doing work to the car in the last few months and as I’m sure you all know its a bit of a pain in the ass.
