## Discrepancy

LEFT FORWARD AISLE EMERGENCY LIGHT UNDER SEAT 3 DOES NOT ILLUMINATE DURING TEST WITH EMER LIGHTS SWITCH IN EITHER ON OR ARM POSITIONS.  WE DID THE EMERGENCY LIGHTS FAIL PREFLIGHT TEST CHARGING PROCEDURE FOR A TOTAL OF ONE HOUR AND STILL OBTAINED THE SAME RESULT. REMOVED AND REPLACED #2 EMERGENCY LIGHTING BATTERY AND PERFORMED CHARGING PROCEDURE AND OPS CHECK OF THE EMERGENCY LIGHTING BATTERY WITH NO DEFECTS NOTED. OPS CHECK GOOD. WORK DONE IN REF WITH AMM 33-50-06.
