Laser Pegs Multi-Model 4-in-1 Red Racer with 5 LED Light Brick & 185 Brick Piece"Build, create, and illuminate with Laser Pegs Multi Models. Assemble four different race cars from this one set Choose which one you want to build first: the Red Racer, the Dragster, the Tri-Racer, or the Beach Buggy. Race to the finish line to win the race, and don't forget to stop and admire this race car's bright red lights Each set comes complete with easy to follow, step by step instructions for you to build 4 model vehicles, 1 at a time, 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 per LED brick, included) and draw a 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 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.
