It's possible to run the and, but after some work I was not able to add the same functionality of attach_lights in my model.

The light need to be declared inside world and linked in robot ?

Here is my code.

It looks like you're putting the light inside `<robot>`, which becomes a `<model>`. But the lights must be in the `<world>`.

Ok, the lights need to be inside world ? I want my robot to work with any world, is that not possible ?

This feature is being actively worked on and should be available in a coming Gazebo 7 release:

Besides putting the <light> in the <world>, you need to wrap your <plugin> tag with <gazebo>. <gazebo><plugin ...=""> ... </plugin></gazebo>

You need to put a light inside your world, as @chapulina told.

Please try to insert a custom light inside your world, like this one:

<light type="spot" name="test_light">
    <pose>0 0 0 0 0 0</pose>
    <diffuse>1 1 1 0.5</diffuse>
    <specular>.1 .1 .1 1</specular>

After this, try using the gazebo tag inside your robot (you missed the gazebo tag):

    <plugin name="attach_light" filename="">

That worked fine by me. Note that I was succeeded only after I updated Gazebo to the 7.14 version.

The feature to spawn a light in any world mentioned by @chapulina ( was released in Gazebo 7.10.Did you have to explicitly specify the light in the world even in Gazebo 7.14?
