LED Traffic Lights Signal Module (Miniature 3-Color Electronic Traffic Signal Block)
Introduce realistic signaling arrays and smart visual indicators into your automation layouts with the premium LED Traffic Lights Signal Module. Engineered specifically for rapid digital prototyping, this compact board stacks bright Red, Yellow, and Green light-emitting diodes into a standardized vertical column, simulating a full-scale municipal traffic light network on your workbench.
Wiring up individual indicator diodes onto standard breadboards requires calculating individual current-limiting resistors and managing a messy web of jumper lines. This module clean-cuts that overhead by embedding integrated protective surface-mount resistors directly onto its rigid circuit frame. It serves as the definitive visual status panel for model railway systems, smart city layout simulations, obstacle warning modules, and interactive microcontroller testing benches.
Key Features
Integrated Three-Color Display Column: Fitted with three high-visibility, clear-lens light-emitting diodes (Red, Yellow, and Green) stacked in a standard top-to-bottom sequence.
Onboard Current-Limiting Resistors: Built with factory-integrated protective surface-mount resistors, allowing you to drive the pins directly from logic gates without burning out the diodes.
Active-High Digital Logic Control: Fully compatible with universal microcontroller inputs; driving any specific control pin to a high level illuminates its corresponding color element instantly.
Streamlined Four-Pin Male Header Array: Breaks down all electrical pathways into a single 4-pin interface row (Common Ground and Three Individual Color Controls) for fast wiring connections.
Sleek High-Contrast Substrate Layout: Machined on a robust, flame-retardant composite circuit plate with a dark finish that minimizes light glare and makes the active signal look exceptionally sharp.
Seamless Customization Support: Developed around an exceptionally flexible circuit footprint. If your specific testing application requires alternative pin configurations, custom board lengths, or unique diode sizing, we can easily customize the module configuration to fit your exact blueprint specifications.

Pinout Connection Blueprint
The 4-pin interface block is clearly etched onto the substrate base to prevent cross-wiring mistakes during fast assembly cycles:
R (Red Control Input): Drive this pin to a high logic level (3.3V or 5V) to illuminate the top Red indicator element.
Y (Yellow Control Input): Drive this pin to a high logic level (3.3V or 5V) to illuminate the middle Yellow indicator element.
G (Green Control Input): Drive this pin to a high logic level (3.3V or 5V) to illuminate the bottom Green indicator element.
GND (Common Ground): Connect this terminal directly to the common negative power reference or grounding rail of your microcontroller.
Common Applications
Smart City & Autonomous Vehicle Tracks: Place multiple signal blocks along miniature road layouts to simulate automated intersection loops using ultrasonic distance modules.
Industrial Relay State Indicators: Wire into automated control chassis to act as a highly visible diagnostic tree (e.g., Red for system fault, Yellow for standby, Green for normal active relay operation).
Model Railway Network Flags: Position along custom model train tracks to act as automated yard flags and block signals, indicating track occupancy or line switching clearances.
Educational Academic Innovation Laboratories: An excellent, highly interactive teaching accessory for introducing vocational electronics students to basic digital logic, timing loops, and state-machine array code structures.
