genius747, The switches you mentioned are 'EXT LT' (external lighting). You can also find 'INT LT' to right of APU, and then there is 'SIGNS'....
LAND (landing lights) is the equivalent of headlights in your car, The lights on NOSE landing gear are supplementary to "LAND" lights on both side of the fuselage. There are 2 "TURN OFF" light which shine sideways and forward, one on each side.
