Auxiliary lights

[Lancia Beta 2000]

Hi guys,
I would to mount a pair of auxiliary main beam lights in my beta coupe  without to hole the bumper.

Do you know how I can do?
...maybe with a pair of brackets like these

but I don't know who sell it in Europe..
A sort of these.. but I'm afraid that are too small..
