A lightpoint (glowing light source) is a non-physical object that shines a light. Unlike projectors or vehicle headlights, this light type cannot be directed into a beam and can only glow uniformously. The glowing does not cast shadows (only the sun or the moon can) and can go through walls.
A lightpoint is local to the computer where the script has been called; one player could see a light in the dark while another would not have such light "object" created.
Colour set via setLightAmbient determines the outer colour shone by the lightpoint.
The flare is the "colour point" centre that emits light. It can be visible or invisible (set by setLightUseFlare).
The list of all lightpoint commands can be found in the Lights command group category.
