A 320 Lighting
 

In case of Emergency Electric Config in the A320 will there be any external lighting?

Nav Lights at least surely.
Had a quick look in the QRH but couldn't find and reference, but they work off the batts on the ground.

In FCOM; the only lights mentioned in relation to Emer elec config are the Emer cockpit, and Emer cab lights, both of which are always available.

I thought the port landing light was available, but can’t remember where I read that.
