This is the IMO PL04C 22mm Pilot Light Head – a Yellow Smooth Lens Indicator available at SparksDirect for the best price. Purchase this item with confidence at Sparks today.
The IMO PL04C is a 22mm modular indicator head featuring a smooth, yellow lens. In industrial environments, yellow (or amber) is the standard color for "Warning" or "Abnormal" conditions, signalling to an operator that a process has deviated from standard parameters or that a specific caution-state is active.
Constructed from UV-stabilised, impact-resistant polycarbonate, the PL04C is built to withstand harsh factory conditions. It carries an IP67 rating, ensuring it is completely dust-tight and waterproof, even under temporary immersion. Because it is part of a modular system, the lens head clips onto a mounting collar which then houses a separate LED or lamp block. This modularity allows for easy bulb replacement or color changes without removing the entire housing from the panel. The IMO PL04C is a modular pilot light head designed to provide clear, visual status indication on industrial control panels. It is a non-illuminated component—meaning it is the colored lens and housing—that requires a separate LED or bulb element to function.

Frequently Asked Questions
Q: Does this include the LED or bulb?
A: No. The PL04C is the lens and bezel assembly. To make it light up, you will need to purchase a mounting collar and a compatible LED block (available in various voltages such as 24V AC/DC or 230V AC).
Q: What does a yellow light typically represent?
A: According to international standards, yellow signifies an "Abnormal" condition or "Caution." It is commonly used to indicate a motor trip, a tank reaching a high-level limit, or a machine waiting for an operator's intervention.
Q: Can this be used in bright sunlight?
A: Yes. The lens is made from UV-stabilised material to prevent fading and cracking. When paired with a high-intensity LED block, the yellow light remains visible even in well-lit environments.
Who can install this?
Installation should be performed by a qualified electrician or panel builder. The installer must ensure the 22mm hole is clean and that the sealing gasket is correctly seated to maintain the IP67 rating. Wiring the associated lamp block requires knowledge of the control circuit voltage to avoid burning out the light element.
What is this for?
The IMO PL04C is used for Visual Process Feedback:
- Fault Signalling: Indicating a non-critical fault or a warning state in an automated system.
- Status Monitoring: Showing that a specific part of a process is in a "Hold" or "Caution" phase.
- Safety Warnings: Acting as a visual alert before a machine automatically starts or moves.
- Panel Identification: Providing a clear, color-coded reference for operators managing multiple control enclosures.
