At cruise over ZZZ; Flight Attendant called to say lights in both aft lavs were flickering; [and] then went out. Emergency Exit light in aft lav was only light on; and too hot to touch. I passed information to Maintenance Controller and he suggested pulling Circuit Breaker (C/B) H7 on Captain's overhead panel that controls the three Emergency lights in three lavatories. I pulled C/B and had Flight Attendant check; hot light went out. All other operations normal; continued to destination. Maintenance Control suspected light batting [insulation].
Reporter stated the aft Flight Attendant called him after she started noticing an odor that smelled like overheated; melting plastic coming from one of the aft lavatory light fixtures on an A320 aircraft. Concerns about potential cabin smoke or fire developing could have been a greater issue if pulling the Circuit Breakers (C/B) for the aft lavatories Emergency Lights had not shut the lights off and stopped the odor.
