I saw a movie years ago and I strongly believe it was on Lifetime. It was about a young woman who was the caretaker for her brother (whom I believe was autistic). I think her parents had died and she was his caretaker. She had found a new job and gotten a young lady to watch him while she worked but he had a bad episode and broke out the windows. She loved him so much but had become overwhelmed and debated whether she should put him in a home or not. She did end up putting him in one but it was one where he could learn new things. I also think he might have been fascinated with Lights and it might be a part of the movie title. Please help!
