ACR MAKES TAXI ERROR AT TUL; TXWY LIGHTS MAY NOT HAVE BEEN FULLY OPERATIONAL.

Narrative

IT WAS BEGINNING TO GET DARK TAXIING OUT FOR DEP. WE WERE GIVEN CLRNC TO TAXI TO RWY 18L. WHEN EXITING THE RAMP AREA I TURNED ONTO TXWY H INSTEAD OF J. AFTER XING RWY 8/26 I WAS FOLLOWING TXWY CTRLINE LIGHTS BUT COULD NOT SEE ANY TXWY EDGE LIGHTS. I DON'T BELIEVE THEY WERE ON. I WAS ALSO LOOKING FOR RWY EDGE LIGHTS OR SIGNS IDENTING RWY 18L. I DID NOT SEE ANY. IN ADDITION SLOPING TERRAIN IN THIS AREA MADE IT DIFFICULT TO SEE VERY FAR DOWN THE TXWY. IN THIS AREA TXWY H ACTUALLY CROSSES RWY 18L WHILE TXWY J TURNS TO PARALLEL RWY 18L. AT THIS TIME I REALIZED THE TXWY WOULD LEAD ME ONTO THE RWY; WHICH WAS NOT MY INTENTION. I IMMEDIATELY APPLIED BRAKES TO AVOID ENTERING RWY 18L. IT WAS DUSK AND VERY DIFFICULT TO SEE. THE TWR ALSO DID NOT GIVE ANY COM REGARDING USE OF A DIFFERENT TAXI RTE. ADDITIONAL LIGHTED TXWY AND RWY INFO WOULD HAVE BEEN VERY HELPFUL. I DO NOT BELIEVE TXWY H HAD 3 RED LIGHTS ACROSS THE CTRLINE LIGHTING TO IDENT ENTERING A RWY. THIS COULD POSSIBLY PREVENT SOMEONE FROM INADVERTENTLY ENTERING A RWY.
