Is it the brackets or lights that you need?
I bought a pair of used fog lamps from a breaker for 40GBP. Online, + 10GBP postage. I made my own brackets as the lamps were from an earlier model.
In short, fifty Euro is a fair price for lamps, too much for brackets.
It will be all right in the end. If it isn't all right yet, then it is not yet the end..
