“mobile” solution for additional headlights???

Hej, after suggesting that we will be on our way to northern Sweden more often in the next few years and that we met the necessity and added value of the “typical” Swedish additional lights on the cars on the first trip there in December 2015, we would like to have them available in the future on our trips in Sweden. However, all sensible solutions are not compatible with the German registration authorities/TÜV or we do not want 11 months l Ang in D with extremely un-aerodynamic (and rather ugly) headlights driving around in front of the front grill, so that we would be very interested in a “mobile” solution. Of course, the wiring would have to be permanently installed – but with the actual headlights it would be nice if there were a solution that can be installed relatively uncomplicated as soon as you roll on Swedish ground, but which can be dismantled just as quickly and easily, if you get back to German territory I’m not fixed on the classic (large) round headlights either; I could also imagine an LED light bar if this makes things easier. Does someone think that this is feasible and can give helpful hints on how to do something like this or know a suitable solution? Tack så mycket! (Thank you!) 🙂 P.S.: Oh so – vehicle would be a Seat Alhambra 2.0 TDI 4Drive (model year 2016); ex factory with Bi-Xenon headlights, but which in winter in Sch Swedish Lapland is not really enough….
