the differnce is the dot [usa] ones have a reflective piece/strip in them. it does give a safety edge to them,but the oem euro bosch ones have a nicer look [imho] to them.
if you change them you will be happier with the oem ones.THIS has been highly debated here.
i can help you get some at a decent cost if interested.
