Maybe because half of the light output is blocked.
Thats also kinda so you don’t blind everyone on the road

It’s so that they are actually FOG lights.

When there’s a lot of particulate in the atmosphere you want to have light low and wide spread not a lot coming back at you. Just like flipping high beams on in falling snow.

Despite its appearance, fog typically doesn't touch the ground but hovers about 18 inches over the surface. The low placement of the fog lights on a vehicle lets the light beam hit the road without interference. With a sharp cutoff angle in the top of the light housing, none of the beam shines up to reflect off the fog, only illuminating the road ahead. Angled downward, fog lights do not have the “reach" of headlights, but they should light up enough of the road ahead for drivers to slowly make their way to their destination. Since the fog lights aren't just reflecting light back, other drivers are more aware of your presence out on the road, making for a second safety benefit.

The light angle adjustment knob is on the bottom of the fog light. ;)
