Glowing effects in Unity

Here is Diffuse Wrapped shader, written it long time ago.

 Shader "Project/Diffuse_Wrapped" {
     Properties {
         _Color("Main Color", Color) = (1, 1, 1, 1)
         _MainTex("Base (RGB)", 2D) = "white" {}
     }
     SubShader {
         Tags { "RenderType"="Opaque" }
         LOD 200
         CGPROGRAM
         //full shadows
         //#pragma surface surf WrapLambert fullforwardshadows
         //no shadows
         #pragma surface surf WrapLambert
         //#pragma lighting ToonRamp exclude_path:prepass
         inline half4 LightingWrapLambert(SurfaceOutput s, half3 lightDir, half atten) {
             //#ifndef USING_DIRECTIONAL_LIGHT
             //lightDir = normalize(lightDir);
             //#endif
             half NdotL = dot (s.Normal, lightDir);
             half diff = NdotL * 0.5 + 0.5;
             half4 c;
             c.rgb = s.Albedo * _LightColor0.rgb * (diff * atten * 2);
             c.a = s.Alpha;
             return c;
         }
         sampler2D _MainTex;
         float4 _Color;
         struct Input {
             //float2 uv_MainTex;
             float2 uv_MainTex : TEXCOORD0;
         };
         void surf (Input IN, inout SurfaceOutput o) {
             half4 c = tex2D(_MainTex, IN.uv_MainTex) * _Color;
             o.Albedo = c.rgb;
             //o.Alpha = c.a;
         }
         ENDCG
     }
