I personally do not like them, and most of the posts on some other MB sites don't like them either . I know the euros' are hard to find but they do show up once in awhile on ebay . I'd install the US spec if you have them, or buy a set;they are cheap and plentiful. Then search for the euro units.
Those deer can cause a huge amount of damage, have hit 2 in last 10 years. Both times they jumped across a road and it was impossible to avoid contact.
