My CB500 has one of those round headlights with the bolt either side. The other day one of the bolts fell off whilst travelling at about 60, which was fun because it also holds on the tax disc... To cut a long story short, the bolt is now replaced but I adjusted it wrong and the dipped beam is doing a very good job of illuminating trees, the undersides of bridge, birds etc. Is there a method of setting it to not blind people but still provide illumination? I seem to remember something about parking a certain distance from a wall and the top of the beam reaching a certain height. cheers Nick
