Do not buy a bulb unless it is guaranteed that the position, shape and size of the LED exactly match the filament of a bulb, the whole reflector and hence the legal beam pattern is designed around the filament bulb. Here are some interesting videos about different LED bulbs and the presenter has a novel way of getting rid of the ones that don't produce a both good beam pattern and the claimed light output. Some of these bulbs are worse than terrible and it is a wonder they even made it to market. The bulbs in our cars and bike have all passed MOT, the new MOT rules mean they pay particular attention to beam pattern.
