TXWY TKOF IN A DUSK NIGHT OP.

Narrative

FIRST TKOF AT DUSK FROM THIS ARPT; LOTS OF REFLECTION ON INSIDE OF COCKPIT GLASS (TOO BRIGHT); PARKING LOT LIGHTS; ETC; PLUS MY TURN LIGHTS ARE TOO CONCENTRATED ON A SMALL AREA; LITTLE PERIPHERAL LIGHTING. I REQUESTED AN INTXN TKOF FROM 10000 FT RWY; LEAVING ME AROUND 5000-6000 FT OF RWY. EARLIER IN DAY I HAD TAKEN OFF FROM FULL LENGTH WHERE THERE WAS ONLY 1 TXWY. AT THE INTXN THERE ARE 2 TXWYS; ONE HIGH SPD NEAREST RWY AND THE ONE I WAS ON. THERE WAS LITTLE ACTIVITY AT THIS TIME; ONLY ONE LNDG ACFT THAT APPARENTLY MOVED ONTO THE HIGH SPD TXWY; BEFORE REACHING MY INTXN; WHILE I WAS DOING MY RUN-UP. I SAW HIM EXIT WHAT I THOUGHT WAS THE RWY; CONTACTED TWR AND RECEIVED CLRNC FOR TKOF RWY 26L. I FOLLOWED THE YELLOW LINE ONTO WHAT I THOUGHT WAS THE RWY; NOTICED THE WHITE LIGHTS TO MY L; THEY SEEMED A LITTLE FAR BUT THIS WAS SUPPOSED TO BE A 150 FT WIDE RWY; SO I THOUGHT I WAS JUST A LITTLE TO THE R OF CTRLINE. BLUE TAXI LIGHTS WERE NOT APPARENT TO ME BECAUSE OF ALL THE REFLECTIONS AND NOT QUITE DARK TIME OF DAY; FACING W; AT DUSK; I COULD STILL SENSE THE PAVEMENT SO DIRECTION WAS NO PROB. AT LIFT OFF I SAW WHAT I HAD DONE. THERE WERE NO OTHER ACFT IN THE AIR OR MOVING ON THE GND AT THIS TIME.
