2004 Lexus RX330 lighting problems

The head lights on my 2004 lexus rx330 are so concentrated with little or no diffusion of light that when the road is not flat and there is a dip I can't see beyond 20 yards. When the high beams are on there are shadows through the entire field of view. There are distant lines of demarcation between light and dark. I feel that it is a real safety issue.

I purchased a used lexus 2004 rx 330 from a lexus dealership and a 4 months after I noticed a large amount of condensation in the drivers front headlight1 month later while driving at night the 1 headlight went out completely and I discovered a technical service bulletin issued from lexus but no recall. This is clearly a widespread problem and a safety issue, toyota has yet to fix they want me to pay $500 out of a $1800 repair!
