The US-spec headlights on all the European cars I've had have always been worse than the European versions. I've never bothered to look into what US Department of Transportation requirements result in worse lighting.
I don't really modify my cars much but I read plenty from people who do. My past few cars have been Volvos and no matter which model it was people wished they could get their hands on euro headlights. In addition to working better, at least on the Volvos they also look better. The problem making the change is always expensive, partly because of the cost of headlights in general and then shipping them to the US.
I just bought a Volvo S60 R. Amazing car but subpar headlights are one of its flaws. The US versions have a single Xeon bulb that tilts to act as both a low beam and high beam. It doesn't work all that well in either position. The US cars have a daytime running light in the spot where the European ones have a separate high beam. I guess that means daytime running lights aren't used in Europe so I'll explain them. Since the 90s we in the US have been driving around with our headlights on all day. They're on by default in all the cars I've driven that have them and turning them off usually means finding a tiny switch or in my case a little screw you have to turn.
I'd love to replace my lights with the Euro version but buying them new is over $2000. Since we have so many non-US members here I was curious if anybody ever shipped off lights (or other Euro version parts) to friends in the US.
You'd think those kind of arrangements would be better made on an auto-related forum but in my experience there aren't many people outside North America on the English-speaking boards, even for foreign cars.
To save any significant amount of money over buying lights or other parts from the few companies that import them, they need to be pulled from a junked car. Otherwise you're still paying for expensive new lights and maybe just saving a bit on shipping and the importer's profit.
I don't know how common junk yards are in Europe though I'd bet not as common as in the US. Even here (at least in my area) the old "pick 'n pull" yards where you wandered among hundreds or thousands of cars, took off the parts you wanted and paid for them at the office are getting rare. Now places catalog all the usable parts and pull them as requested which adds labor to the price.
I'm not asking for a volunteer to do this for me
but I'm curious about how feasible it would be, say for a more common car. Is getting used car parts relatively easy?
