Spotlights

Can anyone help with my situation with my program. I am making a spotlight for a lighthouse, and I cannot make the spotlight go out and hit the ocean that I have below. All I can make it do is hit directly down the Y-axis. The lighthouse is very tall, and I have tried to move the location of the spotlight way high, but still spot_direction {1.0, -1.0, 0.0} will not make the light go outwards
