Traffic LED Light Module

From the shop's description

Traffic LED Light Module The Traffic LED Light Module evokes the familiar red-yellow-green signal arrangement seen in real traffic lights, compressing that into a small electronic board. Its three distinct LEDs red, yellow and green are stacked vertically, giving you a miniature yet recognizable version of a full-size traffic signal. Despite its compact footprint, the module communicates the same universal visual language of stop, caution and go. Because it uses simple LED indicators rather than bulky incandescent bulbs, the module feels light and sleek. Its minimalist aesthetic a small rectangular board with three glowing lights lends itself well to model setups, educational prototypes or any project that needs a clear, intuitive status display. The module’s straightforward design invites experimentation, offering an easy way to simulate traffic-light behavior without complex hardware. There is something almost symbolic about the module’s simplicity: three glowing dots that carry meaning far beyond their size. In miniature circuits, embedded systems or teaching environments, this tiny module becomes a powerful signal: red demands attention, yellow prompts readiness, green grants permission. In short, it captures the essence of traffic control in a neatly packaged, accessible form. Features: Three-color LEDs: red, yellow, and green. Built-in current-limiting resistors for direct MCU connection. Compatible with 3.3 V and 5 V systems. Common cathode interface with individually controlled LEDs. Logic-HIGH input triggers LED activation.
