A Pilot reported landing on SUA's taxiway at night after a very long day ferrying an aircraft from the Midwest. Contributing factors were distractions from aircraft fuel annunciator lights; environmental lights; fatigue and situational awareness.

Narrative

Flight originated in the Midwest. When I arrived north of SUA approximately 8 miles I cancelled flight following; was told by ATC airport 7 miles at 12 o'clock position. Tuned radio to CTAF; announced my position/intentions several times and also keyed microphone to activate runway lights. AWOS reported PAPI and REIL out of service. Approaching the airport on a modified right base (1500 FT) the master warning light lit up followed by the 'Fuel Transfer' light. As I was cancelling the master warning and turning off the transfer pump; the right side of the cockpit was lit up by a bright white light. This caused me to loose sight of the runway and in the confusion I landed on the taxiway. The day started very early; getting the airline flights to my departure airport; wait time for connections; a fuel stop and finally arriving at SUA. This was over 17 hours that combined with the nighttime; tiredness; lack of concentration and loss of potential awareness all were contributing factors to the occurrence.
