Default Strange Headlight Problem

I just replaced the headlight switch and decided to check the lights before I buttoned everything up. Here's what happens:

Low Beams: Only passenger side comes on
High Beams: All four lights come on as they should

So clearly the driver low beam lamp is ok, but why would this one only come on when I turn the high beams on? I'm thinking it is not an issue with the new switch because the passenger low beam works as it should.

I did not check the lights before I started the project, so perhaps this problem existed before I replaced the switch. I suppose I could put the old switch back in and see.

Try swapping the bulbs first to see if it's a bulb problem.

The outer bulbs have a low beam filament and a high beam filament, the inner bulbs only have the high beam.
