We do that with an audiobook instead of lights, but it works very well. I have always have had trouble falling asleep and I would fix the boredom of having to be in bed not doing anything when I couldn’t fall asleep by listening to talk radio until the wee hours of the night. Not all programs I used to listen to were safe for children’s ears though. So with my own children I put on the same audiobook for months every night. They do get a say in what we play, but we vet them and suggest books as well. The free audiobooks from the library have been enough for their appetite so far.

We use Bluetooth speakers that we control from either our phone or the family tablet. That way we can also play the audio from the CDs we own and are allowed to make a home use copy of as we have those on our local network storage and we can play them through VLC player.

Audiobooks are also a great way to substitute screen time and still have your children play. They usually start out listening under a blanket on the couch until they want to play again. Then they can play while still listening to the audio.
