Core Advantages of Our Three-color Signal Lamps
- Integrated Carbon Film Resistor: Each three-color indicator light features an internal carbon film resistor. This provides superior over-voltage protection and ensures consistent brightness across different voltage inputs.
- Versatile Wiring Options: Available in Common Cathode (Negative) or Common Anode (Positive). The 15cm PVC pre-wired leads are color-coded to match the LED colors for rapid, error-free installation.
- Factory-Direct Customization: As a specialized indicator light factory, we support fully customizable voltages and LED color combinations. Standard tri-color options include Red/Green/Blue (RGB) and Red/Green/Yellow (RGY).
- Industrial Build Quality: Constructed with a durable copper alloy shell, PA66 lamp holder, and a high-transparency PC lens. Each unit includes a silica gel O-ring and A3 iron gasket for IP67-rated protection.
Industrial & Commercial Applications
Our three-color indicator light range is the preferred choice for multi-status signaling in:
- CNC automation and industrial control panels.
- Medical diagnostic devices and lab instrumentation.
- Server status monitoring and networking hardware.
- Custom automotive dashboards and marine consoles.

Frequently Asked Questions (FAQ)
Q1: Why is the built-in resistor important for a three-color indicator light?
The carbon film resistor regulates the current flow (rated at 20mA). Without it, direct connection to high-voltage sources would damage the LED. Our factory pre-installs the correct resistance for your specific voltage (up to 250V), ensuring safety and longevity.
Q2: Can I get a custom color combination like Red/Green/White?
Absolutely. While Red/Green/Blue is standard, our factory specializes in custom LED color configurations to meet your specific machine status requirements.
Q3: What is the difference between Common Anode and Common Cathode?
In Common Cathode, the black wire is the negative (-) terminal. In Common Anode, the black wire is the positive (+) terminal. This flexibility allows our indicator lamp to integrate with various PLC or control circuit logics.
Q4: Is the 8mm to 16mm range waterproof?
Yes. Every three-color indicator light in our series is equipped with a high-grade silica gel O-ring, providing excellent protection against water and dust ingress, making them suitable for outdoor or wash-down environments.
Q5: How long is the pre-wired lead, and can it be extended?
Standard units come with 15cm of PVC wire. For wholesale or B2B orders, we can customize the wire length, gauge, and even add terminal connectors according to your assembly line needs.
Q6: What certifications do these indicator lights have?
Our products are CE and RoHS compliant. We adhere to strict quality control standards, with each unit supporting an insulation and voltage resistance of up to 1800V for 5 seconds.
