I am sick of this c**p that headlights do not need to be reaimed when the bulb is replaced. THINK! Perhaps this is why so many of you drive around with misaligned headligts. Let's think about what a sealed beam headlight looks like. Even if the glass case was of uniform thickness and shape, the filament is little piece of wire held in place by other thin pieces of metal. This is supposed to be at the focus of a parabola to get a well focused beam. Even minor variations in the placement of the filament will change the beam direction. I have changed lots of headlights (without disturbing the aiming screws) and every time the beam has been way off.
