Transparent shader with color property and no lighting help

Hi,

I found the transparent diffuse shader online, but how do remove the lighting from it?

or if there is a shader out there with

Transparency, Color property (to change the alpha val) and no lighting please let me know

 Shader "Transparent/Diffuse" {
 Properties {
     _Color ("Main Color", Color) = (1,1,1,1)
     _MainTex ("Base (RGB) Trans (A)", 2D) = "white" {}
 }
  
 SubShader {
     Tags {"Queue"="Transparent" "IgnoreProjector"="True" "RenderType"="Transparent"}
     LOD 200
  
 CGPROGRAM
 #pragma surface surf Lambert alpha
  
 sampler2D _MainTex;
 fixed4 _Color;
  
 struct Input {
     float2 uv_MainTex;
 };
  
 void surf (Input IN, inout SurfaceOutput o) {
     fixed4 c = tex2D(_MainTex, IN.uv_MainTex) * _Color;
     o.Albedo = c.rgb;
     o.Alpha = c.a;
 }
 ENDCG
 }
  
 Fallback "Transparent/VertexLit"
 }
