M22-L-Y-24
Active22mm Yellow LED Indicator Light 24V M22
Eaton M22 yellow warning indicator with 24V LED.
Common Applications
Yellow = warning per IEC 60204-1. Pre-fault condition, filter dirty, level low. Completes the traffic light: M22-L-G green + M22-L-Y yellow + M22-L-R red.
Research Notes
1. Overview
The Eaton M22-L-Y-24 is a 22.5 mm yellow indicator (pilot) light for the M22 / RMQ-Titan system — a flush, illuminated status light (not a pushbutton) running on 24 V AC/DC. The M22-L line is the indicator-light family; Y = yellow. As with M22 modular parts, a complete indicator combines the lens/light head (M22-L-Y) with a fixing adapter (M22-A) and an LED element (M22-LED-24-…) — the "-24" denotes the 24 V variant. It shows machine/process status (e.g. warning/attention for yellow).
2. User Sentiment
M22/RMQ-Titan indicators are standard, robust panel status lights — valued for the clean modular system, bright LED elements, and matching the M22 pushbutton aesthetic. The main practical point is modular assembly: order the correct lens color, LED voltage (24 V here), and fixing adapter. Yellow conventionally signals caution/attention/abnormal status.
3. Real-World Applications
Panel/machine status indication — yellow for warning/attention/caution conditions (e.g. a fault pending, a non-normal state), alongside M22 pushbuttons and other indicators on a control panel.
4. Technical Specifications
- Type: M22/RMQ-Titan indicator (pilot) light, 22.5 mm, flush — not a pushbutton
- Color: yellow
- Voltage: 24 V AC/DC (LED element)
- Cutout: 22.5 mm
- Construction: modular — lens/head (M22-L-Y) + LED element (M22-LED-24-…) + fixing adapter (M22-A)
- Approvals: UL, CSA, CE
5. Ordering & Compatibility
Fits 22.5 mm cutouts, M22 system. Confirm the LED voltage (24 V) and that you have the lens + LED element + fixing adapter (some catalog numbers bundle these; others are the lens only). Other colors/voltages are separate M22-L codes.
6. Known Issues
No notable reliability issues. Practical care: match the LED voltage (24 V, not 120/230 V), confirm the modular pieces (lens + LED + adapter) are all present, and remember it's an indicator light (status only), not a pushbutton.

Installation Quick Reference
Panel cutout: 22.5mm. Insert from the front, secure with mounting nut.
LED module: Check the voltage rating matches your supply (typically 24V DC or 230V AC). Connect to PLC digital output or relay contact for status indication.
Color meaning (IEC 60204-1): Green = normal/running. Red = fault/danger. Yellow = warning/caution. Blue = mandatory action. White = neutral/general.

Troubleshooting
Light is dim or flickering
Check supply voltage matches the LED module rating. Low voltage causes dimming. If voltage is correct, the LED module is failing — replace it. LED modules have finite life (typically 50K-100K hours).
Light doesn't turn on
Verify voltage at the terminals with a multimeter. Check the PLC output or relay driving the light. LED modules are polarity-sensitive on DC circuits — try reversing the leads.
