On gates A24 - A23 - A21 - A17 in IND the paint for the lead in lines has worn off to the point they are no longer discernible (ESPECIALLY at NIGHT).  The aircraft stop marks are non-existent because of paint wear off. We've had multiple incidents where aircraft inadvertently parked wrong and had to hook up push back tractor and tow them to correct spot because employees were unable to see correct stop marks.
An IND aircraft marshaller reported the lead-in lines and stop marks at Gates A17; A21; A23 and A24 have faded to non-detectability resulting in aircraft being stopped at incorrect locations and then being pushed to accessible locations.
