The UK RHD and EU LHD cars have different beams. The car's headlamps in Hungary has the LHD beam.
I called the Hungarian Lexus dealer and they said that I have to change the RHD car headlamps if I want to register in Hungary. The cost is very expensive. About Ł1,200.
After I called the Hungarian Traffic Authority and I told them that Lexus RX400h beam are flat. They said that they do not care it. I need the LHD beam not other solution is available.
So, I have two option. I have to buy an LHD headlamps or I have to find a xenon specialist who can convert the RHD headlamp beam to LHD headlamp beam.
So far I could not find a man in England who deal with such things (re-alignment).
