How to adapt US boat trailer electrical hook up to european standards and use on euro roads? - boat trailer gliders

I have a tandem axle trailer Karavan boat with a 4-pin DC-output for the car. It must be sent to Europe, and I need to know what changes are needed in the trailer (including a connection to the European automotive lighting for the signal) for use on European roads. Is there a simple solution?
