.IX Header "DESCRIPTION"
Set the OpenGL or Direct3D per-vertex light source enable.  See the GL_LIGHTn description on the OpenGL glEnable manual page for details.
.PP
The standard reset callback sets the LightEnable state to bool(false).
.PP
The index ndx identifies the light source and must be greater or equal to zero and less than the value
of \s-1GL_MAX_LIGHTS\s0 (typically 8).  DirectX 9 supports 8 light sources.
