I bought a pair of those rubber headlight surrounds that are popular in Eastern Europe but I am at a loss to how they fit on? They don't come with any fittings just two long tabs with holes in the end that extend outwards which look like they some home tuck behind the headlamp. I've tried just pushing them around the light thinking that just friction holds them in place but they don't fit well and seem to pop loose. Has anyone fitted these before that could Possibly give me a clue?
