Narrative:

The near miss occurred on [the] gate. There was a catering truck parked on the correct side of the osz (operational safety zone). Once given the 'all clear' signal with the lighted safety wands from both guide men I began to marshal the aircraft. During marshaling; I was given an abrupt signal to 'stop' the aircraft from one of the guide men. I immediately signaled 'stop' to the captain. With the height of the catering truck and the low winglet of the 737-800 this becoming way too close for a safe operation at this gate based on the osz current lines. The lines need to be extended to make it safer for aircraft at this gate. The aircraft was always on the yellow guide line during the entire time I was bringing the plane in. The lines painted marking the osz are faded and can be tough to see for all ground personnel; especially at night and when there is a wet surface from the rain earlier in the night. In addition; catering drivers need to be informed of the proper spots to park their vehicles. This potential hazard could easily be corrected in the future.
