DURING A NIGHT APCH TO RWY 1L AT LAS ARPT; THE CLRNC RECEIVED WAS 'CLRED TO LAS VOR; DIRECT; EXPECT THE VISUAL TO RWY 1L.' PLT RECEIVED AND ACKNOWLEDGED; THE PLT THOUGHT HE HAD THE ARPT IN SIGHT AND RPTED; AT THAT TIME HE WAS CLRED FOR THE VISUAL APCH. I LEFT AND ACKNOWLEDGED; 2 MINS LATER; APCH ADVISED 'YOU ARE 3 MI W OF RWY 1L CTRLINE.' PLT ACKNOWLEDGED. ATC THEN ASKED IF THE ARPT WAS IN SIGHT. PLT ACKNOWLEDGED 'YES.' ATC THEN ASKED 'DO YOU HAVE THE ARPT?' AGAIN THE PLT STATED 'YES.' ATC THEN ASKED 'IS THERE A CONFLICT WITH YOUR POS AND MINE?' THE PLT STATED 'YES.' ATC ISSUED A 90 DEG TURN TO THE R UNTIL FURTHER ADVISED. 2 MINS LATER; UNTIL THE PLT RPTED ARPT IN SIGHT; ATC ADVISED 'CLRED FOR THE VISUAL RWY 1L; CONTACT TWR.' PLT COMPLIED AND LANDED WITHOUT FURTHER INCIDENT. CONCLUSION: THE PLT FLIES ON A REGULAR BASIS TO LAS AND IS FAMILIAR WITH THE AREA. VISUAL APCH TO RWY 1L; HOWEVER; IS NOT OR SELDOM USED. THE PLT WAS IN ERROR WHEN THE INITIAL RPT OF ARPT IN SIGHT AND WAS GOING TO THE WRONG LOCATION; THINKING IT WAS THE ARPT. ATC'S INTERVENTION WAS QUICK AND APPROPRIATE. CLRLY THE PLT WAS MISTAKEN AND LOST SITUATIONAL AWARENESS AND POS OF ACFT BECAUSE OF FAMILIARITY OF THE AREA AND COMPLACENCY.
