You need something to reflect.

This may sound trivial at first, but there's a catch: Light sources 
don't show up directly in the image (unless you assign a `looks_like` 
object), nor do they show up as reflections via the `reflection` 
mechanism (or as refractions, for that matter).

The mechanism by which reflections of light sources are made visible is 
via the specular highlights (`specular` and/or `phong`) mechanisms.

To better control the magnitude of specular highlights, I recommend 
using the `albedo` keyword to get the same scale as the `reflection` 
setting (otherwise the brightness is difficult to control and depends on 
the tightness of the highlights, i.e. the `roughness` and/or 
`phong_size` parameters). To make them conform to the Fresnel law you 
need to specify `fresnel on` right in the `finish` block (as opposed to 
the `reflection` block). (Requires POV-Ray v3.8.)

I recommend `specular` (being the more realistic model) with a very low 
`roughness` setting.
