Rick is correct. Euro lights were and are superior to USA headlamps, yet no more powerful wattage wise, and certainly not as bright as HIDs. The required projection pattern of light in USA is simply inferior, yet the demonstrably superior European lighting is not strictly legal per US federal standards (but allowed in most states, as I understand it). My opinion was established from living in Germany (and France, but then seeing at night there was not very important -- 25 watt max yellow high beams back in the 60's, as I remember). Drove both US and European cars there.
