Description
Small cities are built one intersection at a time. This is yours.
The Signal Maker brings real engineering into the brick-built world. Compatible with standard building blocks, this self-locking ABS kit assembles into a working street traffic light with an integrated IC chip that runs the full cycle on its own — green for fifteen seconds, three amber blinks, fifteen seconds of red. Exactly like the intersection outside your window.
Power comes from a USB 5V source — a phone charger, a laptop port, or the power bank already in your bag — so the intersection keeps working long after the build session ends. It is the difference between a model that sits still and a diorama that behaves like the real city.
With 14+ recommended age and ABS plastic that clicks together with satisfying precision, it suits builders, educators, and anyone who ever wanted to control the traffic. The finished signal stands as a desk centerpiece that never stops being fascinating to watch.
The city may not run on schedule. Yours will.

Frequently Asked Questions
Q: Does the traffic light cycle automatically?
A: Yes — the integrated IC chip runs the full sequence automatically: green for 15 seconds, three amber blinks, then 15 seconds of red.
Q: How is it powered?
A: Via USB 5V — connect it to a phone charger, computer USB port, or power bank. No batteries are required.
Q: Is it compatible with other building blocks?
A: Yes. It is designed to be compatible with standard building block systems, extending existing street and city sets.
Q: What age group is it for?
A: Recommended for ages 14 and up, though younger builders can assemble it with adult help.
Q: Can I connect multiple sets?
A: The USB power design makes it easy to add several signals across a larger diorama, each running its own cycle.
Q: Is the plastic safe and durable?
A: Yes — the ABS plastic is certified (3C) and the self-locking bricks hold firmly through repeated assembly and display.
Q: How long is the USB cable?
A: The set includes a standard USB power cable long enough to reach from a desk outlet or laptop port to the signal, keeping your build flexible.
Q: Is it compatible with my existing city set?
A: Yes — the bricks are designed to be compatible with standard building block systems, so the signal connects seamlessly with street plates, cars, and buildings you already own.
Q: Can the light cycle be changed?
A: The IC chip runs a fixed realistic cycle (green 15s, amber 3 flashes, red 15s) — the same logic used at real intersections.
Q: Is it safe for children to use?
A: The set is recommended for ages 14 and up; younger builders should assemble with adult supervision due to small parts and the USB power connection.
