Narrative:
Failure of landing gear indication. On final in stl; after we put the landing gear down and had 3 green lights; the red landing gear/lever disagree message appeared. We went around and ran the appropriate checklist. As directed by the QRH; we returned for a second attempt; and got the same thing; 3 green lights and landing gear/lever disagree message. This time the tower controller saw that the nose gear doors were open; but the nose gear didn't appear to be extended. We went around again and called maintenance. They suggested we try the electrical override gear extension; we did and the landing gear/lever disagree message went away and the 3 green indication remained. We then made a low pass down the runway to get a visual confirmation from the tower. The tower controller said the gear appeared to be down; we landed without incident. Tower controller noticed the nose gear wasn't extended. 2 go around's; first one for the initial EICAS message; 2ND when tower notified us the nose gear wasn't down. QRH should direct crew to use the abnormal gear extension no matter when the EICAS message appears.

Narrative: FAILURE OF LNDG GEAR INDICATION. ON FINAL IN STL; AFTER WE PUT THE LNDG GEAR DOWN AND HAD 3 GREEN LIGHTS; THE RED LNDG GEAR/LEVER DISAGREE MESSAGE APPEARED. WE WENT AROUND AND RAN THE APPROPRIATE CHKLIST. AS DIRECTED BY THE QRH; WE RETURNED FOR A SECOND ATTEMPT; AND GOT THE SAME THING; 3 GREEN LIGHTS AND LNDG GEAR/LEVER DISAGREE MESSAGE.

THEY SUGGESTED WE TRY THE ELECTRICAL OVERRIDE GEAR EXTENSION; WE DID AND THE LNDG GEAR/LEVER DISAGREE MESSAGE WENT AWAY AND THE 3 GREEN INDICATION REMAINED. WE THEN MADE A LOW PASS DOWN THE RWY TO GET A VISUAL CONFIRMATION FROM THE TWR. THE TWR CTLR SAID THE GEAR APPEARED TO BE DOWN; WE LANDED WITHOUT INCIDENT. TWR CTLR NOTICED THE NOSE GEAR WASN'T EXTENDED. 2 GAR'S; FIRST ONE FOR THE INITIAL EICAS MESSAGE; 2ND WHEN TWR NOTIFIED US THE NOSE GEAR WASN'T DOWN. QRH SHOULD DIRECT CREW TO USE THE ABNORMAL GEAR EXTENSION NO MATTER WHEN THE EICAS MESSAGE APPEARS.
