Before I start I did try a seach (just so that doesn't get mentioned) and it turned up nothing.....

I have an '02 A4 and need to replace the rear blinker/marker bulb....However, I can't find a part # for it anywhere....I checked on Sylvania.com and it says its a 7506 but its not....I checked the owners manual and it says take it to the dealer (no thanks)....Oh, and ultimately I want a hyper white bulb for it and not an amber one....Any help would be greatly appreciated!!!!!.......One more thing, I noticed the rear blinker/marker and back-up bulb look the same but the little posts on the bottom are spaced different....

 

anyone???
