As far as know you cant do this. When the app goes to the background, apple allows only limited amount to resources to your app & allows your app limited freedom.
For example, you can play audio when your app is in background. You can have network access (for any downloads etc.) when your app is in background. So don’t think its possible to keep LED lit when the app goes to background.
Correct me if i am wrong or would love to know how you eventually solved this problem..
