But currently I have this:

How can I do this?

My light point and ray initialization


		debug = new Box2DDebugRenderer();
		this.texture = new Texture("sprites/water.png");
		this.camera = new OrthographicCamera(Gdx.graphics.getWidth(), Gdx.graphics.getHeight());
		this.camera.setToOrtho(false);
		this.renderer = new SpriteBatch();
		
		this.map = new TileMap(20, 20);
		this.map.generateAllSame(new Texture("sprites/sprite.png"));	 
		
		this.world = new World(new Vector2(), true);
		
		this.createBodies();
		
		
		RayHandler.setGammaCorrection(true);
		RayHandler.useDiffuseLight(true);
		this.ray = new RayHandler(this.world);
		
		this.ray.setAmbientLight(0.1f, 0.4f, 0.2f, 0.1f);
		this.ray.setCulling(true);
		this.ray.setBlurNum(2);
		camera.update(true);
		
		
		this.spriteLight = new PointLight(ray, 1000, Color.CYAN, 5, 1.f, 1.f); 
		this.spriteLight.attachToBody(this.bodies.get(1), 0, 0);
		

ConeLight?

Yes cone light
is it possible with box2dlights?

It’s open source for reason. So you don’t have to work against black box.
