Narrative:

Before takeoff, I checked my radio with another aircraft in the pattern. After takeoff, climbed to 3000 ft and contacted gr approach numerous times and lan approach also. My transponder was on 1200 not blinking. I set it to 7600 for several mins and to 7700 also. I was approaching lan and observed emergency lights from vehicles on either side of runway 10R. I turned from base to final about 4 mi out and turned my landing light switch on. My total focus was landing on the runway between the fire and security vehicles. If there was a light from the tower I didn't see it. I followed a security officer to an FBO where I spoke on the phone with a gentleman from lan control tower and explained my circumstance, and my destination was ZZZ, us. He advised to follow the security vehicle to runway 10R, put code XXXX in my transponder, and watch for the green light from the tower for takeoff, which I did and had a quiet and uneventful flight. I spoke with ATC personnel and thanked them.
