How can I add self Illumin to that shader?

Hi,

I need the shader Transparent > Diffuse to be self Illumin. How can I do that?

I have that custom shader that makes the same as the shader Transparent > Diffuse :

How can I add self illumin ?

Thanks !

smthing like this?

Shader "Transparent/Diffuse with Self Illumination" {
Properties {
	_Color ("Main Color", Color) = (1,1,1,1)
	_MainTex ("Base (RGB) Trans (A)", 2D) = "white" {}
	_IlluminationPower ("Illumination Power", Range(0, 1)) = 0.2
}

SubShader {
	Tags {"Queue"="Transparent" "IgnoreProjector"="True" "RenderType"="Transparent"}
	LOD 250

CGPROGRAM
#pragma surface surf Lambert alpha

sampler2D _MainTex;
fixed4 _Color;
fixed _IlluminationPower;

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;
	o.Emission = c.rgb * _IlluminationPower;
}
ENDCG
}

Fallback "Transparent/Diffuse"
}
