Spot Light fading out over time

Hi, i am trying to create a game that has a spot light that the character stands in and the light slowly diminishes over time, so it would slowly get smaller and smaller until its darkness, i have looked around the internet and their does not seem to be any help so i was wondering if you could give me a link or an explanation or video tutorial would be helpful thanks.

This can be accomplished using a light function or through direct blueprint manipulation of the light’s properties.

These should get you in the right direction:
and these should get you a good understanding of setting up different types of blueprints:

thanks Is their a way i can edit those to turn off in a set timer? anyone know a blueprint for it or something? thanks
