Your lights are probably being culled by the far clipping plane. Modify
the distance using the setNearFar() method of your pfChannel. A word of
caution here though the near and far clipping planes control the
granularity of the zbuffer. Stretching the far clipping plane way out
will cause popping and flickering of distant objects an effect know as
zfighting.
Ultimately you may need to artificially offset your light points so that
they can be seen from the proper distance. Or you could draw them with
the zbuffer turned off after the framebuffer has been cleared.
