GA SMA MISTOOK WARNING LIGHTS ON TOP OF THE HANGAR AT 022 FOR VASI LIGHTS AND ALMOST OVERSHOT THE ARPT.

Narrative

ON A CLEAR NIGHT APCH TO COLUMBIA ARPT RWY 35; PAVED; LIGHTED; 4060' LONG AND 2112' MSL FLT ELEVATION; I WAS AT PATTERN ALT 3112' MSL; 1000' AGL; LINED UP WITH RWY AND BEGINNING DSCNT WHEN I NOTICED 2 RED LIGHTS WHICH APPEARED TO ME AS ONE OVER THE OTHER. AT THAT ALT I ASSUMED THEY WERE THE VASI LIGHTS INDICATING THAT MY APCH WAS LOW; SO I SLOWED MY DSCNT TO AVOID HITTING AN OBSTRUCTION IN THE DARK. UPON NEARING THE END OF RWY 35; I THEN NOTICED THAT THEY WERE RED OBSTRUCTION LIGHTS ON 2 HANGARS TO THE LEFT OF THE RWY. I THEN APPLIED FULL FLAPS; MADE A STEEP DSCNT AND TOUCHED DOWN ABOUT MIDFIELD; STILL GIVING ME PLENTY OF ROOM TO STOP MY SMA AND AVOID A GO AROUND THROUGH THE DARK VALLEY AHEAD. THE NEXT DAY I CONTACTED THE ARPT MGR AND VOICED MY CONCERNS. HE SAID PLTS HAD BEEN NOTIFIED THAT THE VASI'S WERE OTS; THE RED LIGHTS WERE REQUIRED BY FAA AND THERE WAS NOTHING HE COULD DO ABOUT IT. ALTHOUGH A TENANT AT THAT ARPT; I DO NOT RECALL BEING NOTIFIED BY HIS OFFICE OR BY NOTAM; BUT MY REAL CONCERN IS A VISITOR WITH A FASTER LNDG AIRPLANE THAT MAY NOT KNOW THE TERRAIN AS WELL AS I DO. THERE MAY BE AN ACCIDENT--PLEASE CHK IT OUT.
