Your Lego creations can now do so much more with Brick Brites, the Lego compatible bricks that light up. The bricks are available in three different colors- red, blue, and green and allow you to do such cool things as make light-up emergency vehicles:
They fit right in to your existing sets, no problems. The bricks only light up when you tap them and are good for 100 hours of light, so that should last a very long time. A tiny LED inside the brick does the lighting. Pretty cool stuff, a whole new dimension to Lego (and other compatible major brick building brands).
