Either a table with the properties listed below or an [[Types/table|array]] of tables with the below properties. Specifies a light source.
== Mandatory properties ==
=== type ===
'''Type''': [[Types/string]]
'''Default''': "basic"
Either "basic" or "oriented". If the type is "oriented", the following properties are read additionally to the other properties:
* picture - [[Types/Sprite]], mandatory
* rotation_shift - [[Types/RealOrientation]], optional
=== intensity ===
'''Type''': [[Types/float]]
Brightness of the light in the range [0, 1] where 0 is no light and 1 is the maximum light.
<syntaxhighlight lang="lua">intensity = 0.5</syntaxhighlight>
=== size ===
'''Type''': [[Types/float]]
The radius of the light in tiles.
Note, that the light gets darker near the edges, so the effective size of the light seems to be smaller.
<syntaxhighlight lang="lua">size = 15 -- big light source</syntaxhighlight>
== Optional properties ==
=== source_orientation_offset ===
'''Type''': [[Types/RealOrientation]]
'''Default''': 0
=== add_perspective ===
'''Type''': [[Types/bool]]
'''Default''': false
=== shift ===
'''Type''': [[Types/vector]]
=== color ===
'''Type''': [[Types/Color]]
'''Default''': Light has no color
Color of the light.
=== minimum_darkness ===
'''Type''': [[Types/float]]
'''Default''': 0
== Example ==
The light of the orange state of the rail signal.
<syntaxhighlight lang="lua">orange_light = {intensity = 0.2, size = 4, color={r=1, g=0.5}}</syntaxhighlight>
The front lights of the car:
<syntaxhighlight lang="lua">light =
{
  {
    type = "oriented",
    minimum_darkness = 0.3,
    picture =
    {
      filename = "__core__/graphics/light-cone.png",
      priority = "extra-high",
      flags = { "light" },
      scale = 2,
      width = 200,
      height = 200
    },
    shift = {-0.6, -14},
    size = 2,
    intensity = 0.6,
    color = {r = 0.92, g = 0.77, b = 0.3}
  },
  {
    type = "oriented",
    minimum_darkness = 0.3,
    picture =
    {
      filename = "__core__/graphics/light-cone.png",
      priority = "extra-high",
      flags = { "light" },
      scale = 2,
      width = 200,
      height = 200
    },
    shift = {0.6, -14},
    size = 2,
    intensity = 0.6,
    color = {r = 0.92, g = 0.77, b = 0.3}
  }
}</syntaxhighlight>
