Product Description Build, create, and illuminate with MicroSparks! Light up the element of competition with a one-on-one race! You get two exciting vehicles the Red Formula Car and the Ladder Truck within the set. Go ahead and pit one against the other to the finish line or take them on an adventure to new terrain. You make the rules! Each set comes complete with easy to follow, step by step instructions for you to build 2 model vehicles and rebuild again and again! Laser Pegs is the first light up construction system that combines the traditional construction play pattern with the cool element of light. The Laser Pegs pieces enhance the play of other brick-building products to spark imagination and teach children engineering concepts to encourage a more hands-on approach to tasks. With so many options this set encourages creativity for one build or an entire world of laser pegs. If you can imagine it you can build it, with Laser Pegs it’s your imagination… light it up! Once connected to a power base, each Laser Pegs shape feeds the next, to illuminate an enclosed LED so that these incredible structures light up as you build. Laser Pegs work with batteries (3x LR41 button cell batteries included) and draw very low current. The new chip technology with the LED lights allows the batteries to last 4-5 Days if left on continuously. The bricks are programmed that if they are turned on that they will stay at full brightness for about 15-20 minutes, then they will start to dim to conserve battery life. After one hour, they will turn off. Once you start playing with them again, you turn the switch to off, then on and they come back at full brightness. With daily play with the above pattern, you should get almost a year of battery life. Suitable for ages 8 years and over. Safety Warning Not suitable for children under 36months due to small parts which can be ingested and/or inhaled. Choking hazard.
