How to get input_select entity id and save it in a variable in a blueprint

So this is driving me nuts.

Basicly I’m trying to convert the hook lights blueprint, so I can use an input_select contain two lights instead of one specific light.

Input:
    input_light:
      name: (Required) Input select
      description: Select list of lights
      selector:
        entity:
          domain: input_select

Variables:
  input_light_val: !input 'input_light'
  light: '{{ states(input_light_val.entity_id) }}'

Then I want to save what ever entity light that is currently selected in the input_select into a variable:

But I cannot get this to work, any pointer or help here?

the target selector will allow you to choose multiple entities. You can also set the entity type to only allow users to select lights.

input:
    input_light:
      name: Target lights
        selector:
          target:
            entity:
              domain: light

variables:
  input_light_val: !input input_light

I have this input_select in my config that I use to select a light using a button:

#Input light selector
input_select:
  remote_controlled_led_strips:
    name: Hvilken LED strip skal styres
    options:
      - light.fireplace1
      - light.fireplace2
    initial: light.fireplace1

When I pres a specfic button then it toogle the input_select:

      action_button_center_double:
      - service: input_select.select_next
        data: {}
        target:
          entity_id: input_select.remote_controlled_led_strips
      - service: light.turn_on
        data:
          flash: short
        data_template:
          entity_id: '{{ states.input_select.remote_controlled_led_strips.state }}'
