Sorry not rubbish John although I admit results did vary. It just makes plain sense to me why dedicated LED headlamp design requires projector optics to provide accurate and sharp dip beam cutoff, often mandated with a self levelling system. This is way above the relatively crude focussing by a plain reflector and outer lens dedicated to halogen light source.
This in the light of present lobbying to control dazzling from poorly set up systems.
