There's not much to say about the Brick Brites that the pictures don't already say: They're motion activated brick lights (tap them and they flash for about 12 seconds) you can use to make the world a cooler place.
Therefore we decided to write you a poem instead.
An Ode to the Brick Brite by F. Irebox
Beautiful Brick Brite, how I love your blocky body
You have holes in your bottom, but your top is knobby
Available in clear red, green and blue
You’re even (more or less) waterproof too
