switch from US to European position light/turn signal

[saltyfrog]

I moved to Europe from the US and I brought my 2004 Explorer with me. The problem I have is the combined position light/turn signal. In Europe (Switzerland) the position lights must be white/clear and the turn signal amber, therein lies my problem...
I don't know what the difference is between the US and European version is, if it's a different lens housing or something else? I could take it somewhere and have it done but I was hoping I could do it myself, anyone have any ideas?

TIA,
Matt
