Is it nerdy to be an adult and still get really excited about new types of LEGO bricks? We don’t really care because these light-up bricks from ThinkGeek are going on our Christmas list right now. They aren’t an official LEGO product so technically Brick Brites are compatible with “your favorite construction blocks.”

They are many times more expensive than regular LEGO bricks at $10/pair, but think of how much more authentic your airplanes, alien spacecraft and emergency vehicles will be with real flashing lights! They come in red/white, blue/white and green/white and the embedded LEDs last for 100 hours of flashing. But since they only flash when tapped, they can last virtually forever.
