Reviews of OEM Volkswagen ballast

I bought a cheap 2005 mercedes with a burned out headlight. I took the front bumper shell off (kind of a pain), then swapped parts to determine a ballast was bad. I cross referenced part numbers and bought a VW ballast on ebay for $55. Put it all back together and all is good.

Headlights are all perfect now. Both ballasts should site right side up, meaning red part is perfectly downwards and the font on the rear should be right side up (readable if your head wasn't up-side-down in your hood). So anyone else who has this 'V' shape issue probably has the same problem: incorrectly installed ballast (upside down, not in far enough, loose, etc.)
