Bottom fuselage lights always on

Shouldn't these lights turn on automatically only with gear down? Currently they are lit whenever nav lights are on, and that doesn't seem to be the case when looking at the real aircraft photos.

They are part of position lights, together with green and red wingtip lights and white tail light. There's a switch in the cockpit to set them on, off, bright or dim. Energized by 28V DC primary bus. You can check it in  real pics available online, this one for example.
