Hi John.

I live in the UK but imported a LHD model from Germany. Consequently the rear fog light was on the wrong side. I bought the RHS side here in the UK, and then got a local garage to wire up the connectors from the LHS over the the RHS. As all the correct bits were in the light fitting, all I had to do was put the bulb in. It took the garage about 30 mins.

The company I deal with is called Lancaster Mercedes Benz (franchised), you would need to speak to the spare parts dept. Their phone is 0044 1992 514444 and their email is mercedes@hertford.lancasterplc.com

I've given this address out to several people on the site, so they are used to getting calls from the US. Good luck.

Neil.
