## Discrepancy

WHEN PLACING THE EMERGENCY LIGHTS SWITCH IN ARMED POSITION AND THEN CLOSING THE BLACK COVER TO THE CLOSED POSITION,  THE EMERGENCY LIGHTS BECOME UNARMED AS THE UNARMED ILLUMINATES AND THE EMERGENCY LIGHTS SWITCH IS FORCED BACK TO OFF.   REMOVED & REPLACED THE EMERGENCY LIGHTS SWITCH GUARD. OP CHECKED GOOD IAW AMM 33-51. OK FOR SERVICE.
