For a really effective solution, I would consider using Rubylith. It's what amateur astronomers put over computer screens not to use night vision. You can either put some on your iPad (I've heard that touch works fine through it) or you can put some over your night light instead of the red brake light which I expect puts some white light through.
You can buy a sheet on ebay for a couple of bucks, e.g., from the great guy I link to in
this post if he's still in business.
Using Rubylith will also take care of the problem of white light leakage through black pixels on backlit LCD displays, which is a problem with software-based solutions. And it'll reduce brightness while you're at it. It might however introduce some blurring, depending on how thick the glass on your device in front of the screen is (thicker glass, more blurring).
