Shader lighting not turning on
I've been working with a piecemeal shader that outlines my sprites, however lighting is not affecting the sprites that have the shader on it. I've tried explicitly turning lighting on but I'm not sure what else to do. I am very new at working with unity shaders. Any help is greatly appreciated.
![Shader "Sprites/Outline"
{

{
[PerRendererData] _MainTex("Sprite Texture", 2D) = "white" {}
_Color("Tint", Color) = (1,1,1,1)
_Cutoff ("Alpha cutoff", Range(0,1)) = 0.5
[MaterialToggle] PixelSnap("Pixel snap", Float) = 0
[HideInInspector] _RendererColor("RendererColor", Color) = (1,1,1,1)
[HideInInspector] _Flip("Flip", Vector) = (1,1,1,1)
[PerRendererData] _AlphaTex("External Alpha", 2D) = "white" {}
[PerRendererData] _EnableExternalAlpha("Enable External Alpha", Float) = 0
// Add values to determine if outlining is enabled and outline color.
[PerRendererData] _Outline("Outline", Float) = 0
[PerRendererData] _OutlineColor("Outline Color", Color) = (1,1,1,1)
[PerRendererData] _OutlineSize("Outline Size", int) = 1
}
