What you probably hadn't tried is to use less filtering on the colors of the
light object, still using the high ambient too. It's necessary to make the
object visible to get the ambience to show or else it just gets darker when
more invisible. The light will still shine through but you might need to
increase it's brightness to counteract the less transparent surface. If you
use it as a looks_like in the light_source it will be not cast a shadow, so
that might be unwanted; unless you are using only a pigmented object within
an opaque housing.

You can also add a finish {phong 1 phong_size 0 metallic} so that there is
colored hightlighting on its surface, in which case the filter value could
remain higher (more transparent, filter 1.0 is okay then) and not have to
increase the lights color value. This is actually probably the best
solution.
