The high beams are always in the inside position on N American cars and the aimers are usually at the top and on the outside of the buckets- outside being away from the centre of the car. Think of the old 64 Thunderbolts and their ram air tubes in the inside (high beam) position. The outer or low beams have 2 filaments, that's why they have 3 prongs and they light for both low AND high, while the 2 prong inners have only one filament and light only for high. Capice?
