Combining Lights and switches

light:
  platform: group
  name: Backyard Lights
  entities:
    - light.backyard_1
    - light.backyard
    - switch.01777782ecfabcb6eb71

If you want the switch to actually look like a light you can use this to create a new light from your switch and use that in Lovelace dashboards instead of your switch.

Also in future please format your post correctly.
