Fog Light Switch problems of the 2015 Acura RDX

My low beams are very dim. The original halogen h11 bulbs were yellow so I replaced with sylvania silverstar zxe's. Although light now is white not much of a difference in front of vehicle. Had a mechanic inspect lights and was told some kind of foreign substance is on the back of projector lens and what appears to be finger prints on the front. Possibly poor quality when assembled. Took vehicle to Acura was told the same thing but car is out of warranty with no extended coverage they would replace both headlight assemblies for $1900. It appears other people are having same issue. With recalls on ilx and rlx for same low beam dim light issue. Not safe to drive currently with low beam only. Had fog lights installed use all the time to be able to see.
