## Discrepancy

EMERGENCY LIGHTS TURNED ON AT TOUCHDOWN, STAYED ON FOR 30 SECONDS AND THEN TURNED OFF.  RECEIVED AIRCRAFT AFTER POWER CYCLE, CHECKED BOTH EMERGENCY LIGHT CONTROL AND TEST SWITCHES (FLIGHT DECK AND AFT ATTN PNL) FOR LOOSENESS OR INVOLUNTARY ACTIVATION, COULD NOT DUPLICATE IAW FIM 33-50, AMM 33-51-00-720-801 AND AMM 33-51-00-710-801, ALL LIGHT WORK AND OPS NORMAL. OK FOR SVC.
