Buy Indicating Lamp Online – Pilot Lights for Industrial & Commercial Control Panels

An indicating lamp (also called a pilot light or indicator light) is a compact visual signalling device mounted on control panels, distribution boards, and machine enclosures to communicate the live status of electrical circuits and equipment. Red lamps alert operators to faults or tripped conditions; green lamps confirm normal running; yellow/amber lights indicate standby or warning states; blue and white lights serve custom signalling purposes. At Electrihub, India's trusted electrical e-commerce platform for switchgear and automation products, you can buy Indicating Lamp products from eight world-class brands — all under one roof, with verified specifications, competitive pricing, and fast delivery.

Why Indicating Lamps Are Essential in Every Electrical Panel

Modern industrial plants, commercial buildings, data centres, and infrastructure projects rely on hundreds of control signals every day. Without a reliable indicating lamp at each critical point, operators must rely on meters or software alone — slowing down fault detection and increasing downtime. High-quality LED or filament-based pilot lights provide:

• Instant visual feedback — status visible from several metres away even in bright ambient light.
• Reduced maintenance burden — long-life LED versions last 50,000+ hours with negligible heat emission.
• Standardised colour coding — compliant with IEC 60073 for consistent interpretation across global facilities.
• Panel safety — clearly indicates live vs. de-energised circuits, reducing the risk of accidental contact.
• Easy retrofitting — standard 22 mm and 16 mm cut-out sizes fit existing panels without modification.

Frequently Asked Questions – Indicating Lamps

Q. What is an indicating lamp and how does it work?
An indicating lamp is a small signalling light mounted in a control panel to show the operating status of electrical equipment. It is connected directly across a circuit or via a control voltage signal. When the circuit is energised, the lamp illuminates, providing instant visual confirmation of the state — running, stopped, fault, or standby.

Q. What is the standard mounting diameter for industrial indicating lamps?
The most widely used standard is 22 mm, which is compatible across ABB, Schneider (Harmony), Siemens (SIRIUS ACT), L&T, Havells, and ESBEE ranges. 30 mm is common in older panels and some specific applications; 16 mm is used in compact or miniature panels.

Q. What is the difference between an LED pilot light and a filament pilot light?
LED pilot lights use light-emitting diodes — they consume very little power (typically under 1 W), generate almost no heat, and have an operational life of 50,000+ hours. Filament (incandescent) pilot lights use a replaceable bulb, have higher power consumption and heat generation, but are often more economical upfront. For new installations, LED is strongly recommended.

Q. Which brands of indicating lamps are available at Electrihub?
