## Discrepancy

FOUND LIGHTED EMERGENCY EXIT SIGNS ABOVE LEFT AND RIGHT FORWARD OVERWING EMERGENCY EXITS WILL NOT ILLUMINATE DURING TEST. BOTH LIGHTS ARE POWERED BY POWER SUPPLY B5-121. REPLACED EMERGENCY LIGHT BATTERY ASSEMBLY IN POWER SUPPLY B5-121 IN REF WITH B717 AMM 33- 51. OPERATIONAL TEST WAS GOOD. OK FOR SERVICE. (LP #8303514)
