Well, there were two main reasons behind my conversion:
#1 Europe hasn't allowed red rear turn signals anymore since 2001. Therefore if you like to register a vehicle in Europe you need to convert to amber turn signals. This can be done by using the back up lamps with an amber bulb. But you need to add an additional back up lamp externally, more or less an ugly solution that disturbs the rear of the vehicle.
Because I do like more integrated solutions I was looking for Explorer 'export' tail lamps.
#2 When I first laid eyes on a new '06 Explorer in late '05 I was not amused... It was a gold XLT. Fender lips were dark grey, door handles were flat black and tail lamps were partially high gloss black. Plus the tail lamps look like Volkswagen Minivan/Passat.

Btw, you can get these 'export' tail lights from every Ford dealer, they are called 'Japan/Australia/Europe' tail lamps and fit '02 to '10 models. Installing these lamps is easy but separate turn signal from conventional brake/turn signal is a little tricky... bat as you can see, can be done.
Will add some pics of the lamps later.
