Icon for muliple lights script

Hi peeps
I have created a script that turns off multiple lights at once. Im using lovelace, but the icon box is rather big, and the icon is of a script. I would like a nice small icon of a light bulb. Thank you

mdi:lightbulb-outline

You can define the height of the icon in the settings of the button bard.

I dont want to define the height, I want a an icon that is light bulb, and not a script icon.

I misunderstood you and therefore assumed that “script icon” meant the icon you defined in the input mask which is displayed smaller than in cards. Never mind.

Read that link, it’ll describe how to customize attributes on any entity. 1 attribute is the icon.
