Narrative:

I was using approach control, las, 133.95, coming into north las vegas from the northwest from beatty, nv. I was released by las approach to go to north las vegas tower. I did not contact the tower for 2-3 mins as I was still trying to determine where the airport was, and being sure I was not in the TCA. I contacted the tower with ATIS information and found myself off the approach end of the active runway at approximately 2.5 mi. With the help of the tower instructions I flew toward downtown las and entered downwind with no further problems. One aircraft flew overhead by approximately 300' on final approach while I was trying to get oriented to the airport and to enter downwind. At dusk or night the north las vegas airport is very hard to find and distinguish with all the nearby freeway lights. To overfly the field and maintain VFR altitude sep is tough when the TCA is 4500-5000'.
