## Discrepancy

DURING DESCENT THE FWD EQPT SMOKE EICAS MESSAGE AND EQUIPMENT COOLING SMOKE ANNUNCIATOR LIGHT ILLUMINATED. FOLLOWED QRH BOTH LIGHTS STAYED ILLUMINATED. CONTACTED ATC AND DECLARED AN EMERGENCY AND REQUESTED CLEARANCE DIRECT TO KCVG. WE WERE CLEARED DIRECT TO THE AIRPORT AND TO DESCEND TO 4,000.  SUBSEQUENTLY REQUESTED TO LAND 36R. 36R ALLOWED US TO PROCEED DIRECTLY TO THE AIRPORT FOR A STRAIGHT IN APPROACH.  AFTER ACCOMPLISHING ALL THE CHECKLIST ITEMS IN THE QRH, THE “FORWARD EQPT SMOKE” AND OVERHEAD “SMOKE” LIGHTS REMAINED ILLUMINATED. WE DID NOT HAVE SMOKE IN THE COCKPIT! WE FLEW A VISUAL APPROACH TO RUNWAY 36R. AFTER LANDING, WE TURNED OFF THE RUNWAY AT T6 AND STOPPED. BECAUSE BOTH SMOKE LIGHTS REMAINED ON, WE ELECTED TO POWER DOWN THE AIRCRAFT AND BEGIN EVACUATION. AIRCRAFT GROUNDED BY MAINTENANCE. MAINTENANCE TROUBLE SHOT SYSTEM. DURING T/S FOUND THAT EQUIP SMOKE LIGHT EXTINGUISHED AND MESSAGE CLEARED. FOUND THAT EQUP COOLING TEST SMOKE LIGHT & EICAS MSG.
