## Discrepancy

ON PREFLIGHT FOUND EMERGENCY LIGHTS ASSOCIATES WITH BATTERY PACK NUMBER 1 NOT ILLUMINATING.  PREFORMED EMERGENCY LIGHTS FAIL PREFLIGHT TEST QRH. AFTER 30 MINUTES THE LIGHTS ALL ILLUMINATE, HOWEVER FOUND LIGHTS ON BATTERY PACK WILL NOT SHUT OFF IN THE OFF POSITION.  ATTEMPTED TO RESET THE G SWITCH.  FOUND G SWITCH BROKEN AND THE RUBBER CAP LAYING ON THE FLOOR OF THE COMPARTMENT. CORRECTIVE ACTION: REPLACED EMERGENCY BATTERY SWITCH. OPS CHECK GOOD. IAW MM 33-50-11
