Probably not. Make sure the rear covers on the headlight assemblies right and left are tight and have their gaskets in place, as well as the Angel Eye cover. The main and pulse main beams have square covers with soft gaskets, and the angel eye itself has an o-ring, and the cover also has a secondary o-ring. This is from a 2007, 760Li, yours may vary.
You will find a lot of shoddy work by dealers who leave things loose, not mounted properly, etc. The assemblies themselves look as if they are completely sealed, so any water inside is due to an opening somewhere that's not designed to be there.
America is a divided country. Liberals and progressives vs conservatives. One side is about fairness, the other side is about fairness. The difference is the definition of fairness.
