## Discrepancy

LOWER EXIT LIGHTS ON EITHER SIDE OF MAIN CABIN DOOR DO NOT ILLUMINATE DURING EMERGENCY LIGHT TEST.  THEY ILLUMINATE WHEN BATTERY POWER ON AND EMERGENCY LIGHT SWITCH TO ON.  OPERATED EMERGENCY LIGHTS BOTH WITHOUT MAIN SHIP BATTERIES AND WITH BATTERIES CONNECTED AND EXTERNAL POWER APPLIED.  NO DISCREPANCIES NOTED.  LEFT A/C EXTERNAL POWER APPLIED FOR EXTENDED TIME TO CHARGE E-LIGHTS BATTERIES.  FINAL OPERATIONS CHECK NORMAL, PER CE-680A MM 33-50-00.
