★ LIGHT-UP YOUR LEGO BUILDINGS, CARS, AND OTHER CREATIONS! UniBlock Light-Up Bricks (RGBY) set includes 8 light-up bricks, 2 of each of the following colors RED, GREEN, BLUE, YELLOW. All bricks emit constant light of one specified color. Add it to any design to make it extra special.
★ USE ANY STANDARD TECHNIC AXLE AS AN ON/OFF SWITCH! You can now incorporate our Light-Up Bricks into your Lego Technic creations. Build a system of gears and axles to turn the lights on and off. Four small axles are included. No more hassle searching for tiny on/off buttons. No more light up bricks that turn on by shaking them (not functional in stationary designs).
★ UNIVERSALLY COMPATIBLE WITH OTHER BRICK BRANDS. UniBlock Light-Up Bricks are 100% compatible with ALL major brands of building bricks and proven to work with all licensed LEGO products including LEGO Classic, LEGO Juniors, LEGO Technic, Laser Pegs, Coby, and Mega Bloks small block types.
★ SMALL SIZE. Other brick brands would normally offer bricks of a large size (2x4 or larger). In many cases those bricks also have a power base attached to them. Each UniBlock Light-Up Brick is independently powered by its own batteries. Our bricks are 2x3 only.
★ REPLACEABLE BATTERIES. Each of the UniBlock Light-Up Bricks (RGBY) has two 1.5V button batteries which can easily be replaced.
