Shader: Light off in CGPROGRAM

How I can turn off light in CGPROGRAM ?
I my goal: shader like Unlit (Light don’t affect the shader)

CGPROGRAM
		  #pragma exclude_renderers gles
	      //#pragma surface surf Lambert
	      #pragma surface surf Lambert
	      struct Input {
	          float2 uv_MainTex;
	          float2 uv_BumpMap;
	          float3 worldRefl;
	          INTERNAL_DATA
	      };
	      float _Shininess;
	      sampler2D _MainTex;
	      sampler2D _BumpMap;
	      samplerCUBE _Cube;
	      
	      
	      sampler2D _Texture2;
		  float _Blend1;
			
		  sampler2D _Texture3;
	      float _Blend2;
			
	      sampler2D _Texture4;
		  float _Blend3;
	      
	      void surf (Input IN, inout SurfaceOutput o) {
	      	
	      	   // Blend between base texture nad blend texture 1
			  fixed4 tex = lerp(tex2D(_MainTex, IN.uv_MainTex), tex2D(_Texture2, IN.uv_MainTex), _Blend1);
			
			  // Blend between base+blend1 texture nad blend texture 2
			  tex = lerp(tex, tex2D(_Texture3, IN.uv_MainTex), _Blend2);

		  // I THINK HERE I NEED TURN OFF LIGHT    
	          
	          o.Albedo = tex.rgb;
	          o.Alpha = tex.a;
	          o.Normal = UnpackNormal (tex2D (_BumpMap, IN.uv_BumpMap));
	          o.Emission = texCUBE (_Cube, WorldReflectionVector (IN, o.Normal)).rgb  * _Shininess;
	      }
	      ENDCG

just add Lighting Off before the CGPROGRAM line
