Rear Fog Lights


Registered User
Currently I live in Germany, and as part of the law out here I need to switch my Fog light to the Right side on my 2004 A4. I have removed the both of the rear lights and and they both look the same. But only a light in the right side cluster. I swapt the lights around to find it did not work. I have a crack in my Left rear light, this might be the problem or does light not get any power?

any got any ideas
