Narrative:
At entry point to boi arsa (aldape summit), electrical went out in aircraft (complete failure). In hopes some residual electrical was available I squawked 7600 on transponder and entered the arsa circled at 1000 ft above tpa around tower and got a red and green light gun signal. I continued circling and got a flashing green signal, so continued circling then thought I got a steady green signal. I entered pattern to correct runway and landed and stayed clear of other taxiing aircraft. Taxied to area to let out passenger. Called tower on telephone and was told I acted correctly. Had aircraft electrical problem repaired. Departed with passenger later in day. I had a hard time distinguishing between flashing green and steady green while circling, apparently they had only given a steady green, but it looked flashing as I circled windows. Boise was the only airport within fuel range where I could get electrical problem fixed.

Title: PLT OF SMA SEL ACFT ENTERED CLASS C AND LANDED AT PRIMARY ARPT WITHOUT COMMUNICATING. A TOTAL ELECTRICAL FAILURE LED TO RECEIVING A LNDG CLRNC BY ATC LIGHT SIGNALS.
Narrative: AT ENTRY POINT TO BOI ARSA (ALDAPE SUMMIT), ELECTRICAL WENT OUT IN ACFT (COMPLETE FAILURE). IN HOPES SOME RESIDUAL ELECTRICAL WAS AVAILABLE I SQUAWKED 7600 ON XPONDER AND ENTERED THE ARSA CIRCLED AT 1000 FT ABOVE TPA AROUND TWR AND GOT A RED AND GREEN LIGHT GUN SIGNAL. I CONTINUED CIRCLING AND GOT A FLASHING GREEN SIGNAL, SO CONTINUED CIRCLING THEN THOUGHT I GOT A STEADY GREEN SIGNAL. I ENTERED PATTERN TO CORRECT RWY AND LANDED AND STAYED CLR OF OTHER TAXIING ACFT. TAXIED TO AREA TO LET OUT PAX. CALLED TWR ON TELEPHONE AND WAS TOLD I ACTED CORRECTLY. HAD ACFT ELECTRICAL PROB REPAIRED. DEPARTED WITH PAX LATER IN DAY. I HAD A HARD TIME DISTINGUISHING BTWN FLASHING GREEN AND STEADY GREEN WHILE CIRCLING, APPARENTLY THEY HAD ONLY GIVEN A STEADY GREEN, BUT IT LOOKED FLASHING AS I CIRCLED WINDOWS. BOISE WAS THE ONLY ARPT WITHIN FUEL RANGE WHERE I COULD GET ELECTRICAL PROB FIXED.
