At night; the north ramp at ROC is somewhat dimly lit.  There is no centerline taxi line in the alley [between Concourse A and B].   As a result; crews have to be especially vigilant because there are airplanes parked on both sides; and the ramp narrows considerably as you approach the terminal.   As we entered the ramp; one of the wing walkers was standing out in the ramp and motioning us toward him.  I realized he brought us extremely close to the tail of another parked B737.  We need a centerline taxi line to follow.
