The bulbs are (or were) "omni-directional" meaning they could be turned 180 degrees.
And you have a condition where low beam is the filament on top - and high beam is the filament on the bottom - no matter how you place the bulb.
Today we have the improvement of 20-35 candlepower bulbs - these are no longer omnidirectional since you want to have the 35 candlepower side on the "bottom" (high beams)
(Think of the filaments being oriented as if in a mirror. Low beam filament is on top but reflects "down" - High beam filament is on the bottom but reflects "up.")
Add to this the problems with repop reflectors (ferrule turns or is not located correctly) and repop bulb sockets (indent on socket not made deep enough so can get turned in the ferrule as one adjusts the "focus" on the back of the headlight shell) and you have a system of "irregular results."
If your filaments are "side by each" then this has happened to you.
