Enabling Lights

Enabling any light requires 2 switches to be ‘on’.
Light > Affects World
and
Rendering > Visibility

Wouldn’t it make more sense to use the simple ON/OFF switch light metaphor?
Or perhaps I don’t understand when you might just have 1 of these 2 options enabled.

Did not test this, but it probably means to affect (or not) other bodies, while itself is visible.
