Light shaders

I want to write a custom light shader for water(so that light reflects off of the surface in little specks), but I haven't been able to find anything on light shaders. All I have is this:

DIFFUSE_LIGHT += dot(NORMAL, LIGHT) * ATTENUATION * ALBEDO;

The default light shader would be a good place to start. Does anyone know where to learn about light shaders, or where I can find the default light shader?
Thanks.
