Narrative:

After landing 10L pit we exited runway at N4. (High speed turn). Ground control asked if we could make a hard right turn to taxi west on taxiway north. About 1/2 way into the turn, first officer and I realized it was going to be too tight. We then made a hard left turn back to face east on taxiway north. While making the left turn, the nosewheel locked in a near 90 degree left turn. The aircraft had to be towed to the ramp. In retrospect, the reason for the nosewheel being locked in that position was contact of a taxiway light. Further checks indicated no aircraft damage. A taxiway light was damaged. Better markings like fluorescent paint would have helped to prevent this situation with this size aircraft. I have always been concerned of the rear wheels in turns. I overcompensated in this case. Supplemental information from acn 231913: as captain started to center tiller to straighten out the airplane, he found that the wheel wouldn't go back to center. Gear was stuck at 90 degrees left. Inspection of the nosewheel showed no damage -- it had merely gone over center and got stuck there. Aircraft was inspected and taxi checked. On following flight taxiing out, we both noted that practically all the yellow lines were nearly invisible.

Title: AN MLG ACR CREW HIT A TAXI LIGHT WHILE TRYING TO MAKE VERY TIGHT TURN. TXWY EXCURSION.

Narrative: AFTER LNDG 10L PIT WE EXITED RWY AT N4. (HIGH SPD TURN). GND CTL ASKED IF WE COULD MAKE A HARD R TURN TO TAXI W ON TXWY N. ABOUT 1/2 WAY INTO THE TURN, FO AND I REALIZED IT WAS GOING TO BE TOO TIGHT. WE THEN MADE A HARD L TURN BACK TO FACE E ON TXWY N. WHILE MAKING THE L TURN, THE NOSEWHEEL LOCKED IN A NEAR 90 DEG L TURN. THE ACFT HAD TO BE TOWED TO THE RAMP. IN RETROSPECT, THE REASON FOR THE NOSEWHEEL BEING LOCKED IN THAT POS WAS CONTACT OF A TXWY LIGHT. FURTHER CHKS INDICATED NO ACFT DAMAGE. A TXWY LIGHT WAS DAMAGED. BETTER MARKINGS LIKE FLUORESCENT PAINT WOULD HAVE HELPED TO PREVENT THIS SIT WITH THIS SIZE ACFT. I HAVE ALWAYS BEEN CONCERNED OF THE REAR WHEELS IN TURNS. I OVERCOMPENSATED IN THIS CASE. SUPPLEMENTAL INFO FROM ACN 231913: AS CAPT STARTED TO CTR TILLER TO STRAIGHTEN OUT THE AIRPLANE, HE FOUND THAT THE WHEEL WOULDN'T GO BACK TO CTR. GEAR WAS STUCK AT 90 DEGS L. INSPECTION OF THE NOSEWHEEL SHOWED NO DAMAGE -- IT HAD MERELY GONE OVER CTR AND GOT STUCK THERE. ACFT WAS INSPECTED AND TAXI CHKED. ON FOLLOWING FLT TAXIING OUT, WE BOTH NOTED THAT PRACTICALLY ALL THE YELLOW LINES WERE NEARLY INVISIBLE.
