MLG UNABLE TO PROMPTLY CLR A RWY BECAUSE CAPT WAS UNABLE TO DISCERN JUST WHERE THE TXWY WAS.

Narrative

BECAUSE OF THE GUSTY WIND CONDITIONS FROM THE E; I MADE THE APCH AND LNDG TO RWY 7R AT LAX AT APPROX XA30 PST. DURING THE LNDG ROLLOUT WE WERE ASKED TO EVAC THE RWY ASAP. THE CAPT TOOK OVER THE ACFT (THERE IS NO STEERING HANDLE ON THE COPLT'S SIDE) AND TAXIED OFF THE ONLY 'HIGH SPD' EXIT FOR RWY 7R WHICH IS MARKED NUMBER 28. WE WERE TOLD BY THE TWR (FREQ 120.95) TO REMAIN ON THE TWR FREQ AND TO HOLD SHORT OF RWY 7L WHICH WAS BEING USED FOR TKOFS. AFTER XING RWY 7L THE PROB AREA OCCURS! TXWY 28 NOW CURVES BACK TO THE L AS A 'HIGH SPD' EXIT OF RWY 25R. THE BLUE AND GREEN TAXI LIGHTS ARE OVERPWRED BY THE BRIGHT LIGHTS OF THE ACR HANGAR AND RAMP AREA! I CALLED THAT WE WERE CLR OF RWY 7L/25R BUT THE CAPT NOW STOPPED AND TURNED THE ACFT BECAUSE I BELIEVE HE COULD NOT SEE THE TXWY. THE TWR SAID WE WERE PROTRUDING ONTO RWY 7L AND HAD TO STOP THE TKOFS AND GIVE US INSTRUCTIONS TO TAXI TO GATE. THIS PROB DOES NOT OCCUR WHEN LNDG TO THE W. THIS AREA; NUMBER 28 AT RWY 7L IS CONFUSING AND IS A PROB COMPOUNDED BY THE BRIGHT WORK AREA!
