The 16mm Mounting Hole Size Indicator Light Five Colors AD16-16D/S is the core model of YAMING's flagship AD16 series, an LED indicator with a standard 16mm panel opening, precisely matching the status signal indication needs of industrial and commercial scenarios. The product features a high-strength flame-retardant plastic shell and high-brightness LED chips. It is compact, stable in performance, supports AC/DC universal voltage and five standard colors, and can cover signal feedback for all scenarios including power supply, operation, fault, and alarm. It is an indispensable basic component in control loops.
Utilizing industry-standard 16mm mounting holes, it perfectly matches various standard panel opening sizes, adapting to compact control panel layouts without requiring additional hole modifications, maximizing versatility.
- Red: Fault/Alarm signal
- Green: Power on/Device running normally
- Yellow: Warning/Status indication
- Blue: Auxiliary function/Standby status
- White: Custom signal adaptation
The 16mm Mounting Hole Size Indicator Light Five Colors AD16-16D/S supports mainstream AC/DC voltages such as 6V/12V/24V/48V/110V/220V, with a voltage fluctuation tolerance of ±20%, adapting to different domestic and international power supply standards, making one unit suitable for multiple scenarios.
- Housing: Flame-retardant engineering plastic, high temperature resistant, anti-aging
- Protection Rating: IP40, dustproof and splashproof, suitable for harsh working conditions
- Operating Temperature: -25°C to +55°C, stable operation in extreme environments
- Service Life: LED light source continuous operation ≥30,000 hours, low energy consumption and maintenance-free
Adopting a twist-lock installation design, no professional tools are required. Simply insert into the 16mm pre-drilled hole and rotate to fix it. Installation can be completed by one person in 3 seconds. Subsequent maintenance and disassembly are simple, significantly improving assembly efficiency.
Case 1: Automated Production Line Status Monitoring (An Automotive Parts Factory in Zhejiang)
In 2023, this factory upgraded its PLC-controlled production line, purchasing in bulk YAMING 16mm Mounting Hole Size Indicator Light Five Colors AD16-16D/S, using a red, yellow, and green color combination: green indicates equipment operation, yellow indicates standby, and red indicates alarm shutdown. Usage Results: Adaptable to workshop temperature variations of -10°C to 45°C, trouble-free operation year-round. High-brightness lights are clearly visible from a distance in noisy workshops. Failure rate is reduced by 90% compared to older indicator lights, halving maintenance costs.
Case 2: Outdoor Distribution Cabinet Signal Feedback (Southeast Asian Photovoltaic Power Plant Project)
In 2024, this project selected the YAMING AD16-16D/S (220V AC, IP40 protection) and installed it in an outdoor photovoltaic distribution cabinet. White indicator lights indicate grid connection status, blue indicates backup power, and red indicates leakage faults. Usage Results: Resistant to outdoor rain and dust, resistant to high-temperature exposure, and operated continuously for 18 months without damage. Wide voltage design adapts to local voltage fluctuations, ensuring stable operation and maintenance of the power plant.

Q1: Can the 16mm Mounting Hole Size Indicator Light Five Colors AD16-16D/S be used long-term in humid and dusty workshops?
A1: Yes. The product has an IP40 protection rating, effectively blocking dust intrusion and light splashes. The shell is made of flame-retardant and anti-aging plastic, suitable for a wide temperature range of -25°C to +55°C. It can operate stably for a long time in ordinary humid and dusty industrial workshops, as long as direct immersion is avoided.
Q2: What is the lifespan of the LEDs on this indicator light, and do they need to be replaced frequently?
A2: The AD16-16D/S uses high-brightness original LED chips with a continuous working life of ≥30,000 hours. Under normal operating conditions, replacement is almost unnecessary. LEDs are low-energy light sources with an operating current of ≤20mA. They are energy-efficient with long-term use and have no light decay issues, significantly reducing maintenance costs.
Q3: What precautions should be taken when installing an indicator light with a 16mm cutout? Can it be used with non-standard panels?
A3: During installation, simply insert the indicator light into the standard 16mm cutout and rotate the nut clockwise to secure it. No additional tools are required. For wiring, distinguish between AC and DC polarities (DC type). If the cutout size deviation of a non-standard panel is ≤0.5mm, it can be adapted using the provided gasket; if the deviation is larger, it is recommended to enlarge the hole to 16mm to ensure installation stability and protection level.
