A plasma nightlight might both look and sound awesome, how can it not? Just beware, from the two one star reviews it seems that the MoMA store is having some quality issues with the nightlight at the moment. That being said, they seem happy to help if things go wrong, so if you don’t mind the hassle of chasing down a replacement, or fixing it yourself (it sounds like a faulty switch), then by all means pull the trigger.

Personally, I never saw the need for nightlights until I found myself extracting a piece of broken tooth from my lip after taking a header down to flights of stairs while looking for a light switch in a dark and unfamiliar apartment in Tokyo.
