When I ordered my 210 car when they first came out back in '96, I paid ONE THOUSAND DOLLARS extra for Xenon headlights only to find that they are Xenon on LOW BEAM ONLY. That will teach me to read the details.
All of them I've seen are low beam only. Since then I've learned that good lighting is all in the reflector shape. If you have an early Benz, use Euros and regular bulbs. If you have a late model, you have no problems, they are the same as Euro.
Have a great day,
