## Discrepancy

EMERGENCY LIGHT AREA LIGHT ON AFT WINDSCREEN ADJACENT TO LAVATORY D HAS WRONG LENS INSTALLED. GROUNDED - YES. INSTALLED LENS WAS MPN 207377-1007 (EXIT NOMENCLATURE, NO ARROWS). PER B737-900 WDM 33-51-22-6 AND IPC 33-26-03-55A THE CORRECT LENS FOR THE LAV D AREA LIGHT IS MPN 207377-1078 (BLANK LENS) AS THIS IS AN AREA FLOODLIGHT, NOT AN EXIT LOCATOR SIGN. REMOVED AND REPLACED LENS AND PERFORMED TEST OF EMERGENCY LIGHT AREA LIGHT AT LAVATORY D PER B737-900 AMM 33-51-01-960-801 - OPS NORMAL.
