theres basically two ways to go about this, you can either create a new light or have a light setup in the character and toggle its visibility.
the first picture below shows the first method of creating light, settings its location, and attaching to the character. the script i setup here creates the light when you enter the volume then if you enter it again it destroys the light. a simple on off kind of thing.
the second picture shows the second method mentioned where the light is added to the character beforehand then you just toggle its visibility. this is a much simpler script to write and setup but has its limitations since it needs to be setup beforehand.
