Why choose local lamps & indicators for your build
When a status light or panel lamp fails, troubleshooting and replacement must be fast. Communica keeps a wide, practical selection of indicator lamps, LED pilot lights, bezel-mounted indicators and stack lights in South Africa - focused on availability, quick branch collection and VAT invoicing for education and procurement. Whether you are a student wiring a control panel, a maker adding visual feedback to a robot, or a technician maintaining production equipment, our local footprint reduces lead time and simplifies returns and paperwork.
What you’ll find in our range
From low-current LEDs and neon lamps to IP-rated indicator modules, our categories cover practical options for panel mounting, PCB mounting and on-cable indicators. Browse related categories and brands to compare form factors and lens styles: Shop by Category, or see our full stock list at All Products.
Common use-cases and fast picks
Practical examples we support every week: student project status LEDs powered from 3.3V microcontrollers, 12V panel indicators for small motor controllers, and multi-segment stack lights for workshop benches. For brand exploration and maker-friendly modules, visit our Shop by Brand page.
Key specifications that decide performance
Selecting the right lamp or indicator is not just about colour and size; electrical ratings, lens optics, mounting cut-out and response time matter. Below is a compact comparison to speed decisions at the bench.
| Type | Typical Voltage | Current | Mounting | Use |
|---|---|---|---|---|
| Panel LED indicator | 3.3V-24V | 2-20 mA | Bezel/cut-out | Control panels, enclosures |
| PCB-mounted lamp | 2V-5V | 1-15 mA | Solder footprint | PCBs, development boards |
| Neon/mini lamp | 110V-230V | µA-mA | Bezel/cut-out | High-voltage indicator |
| Stack light segment | 12V-24V | 20-200 mA | Pole mount | Machine status, visual alarms |
Specification callouts to check
- Rated voltage and maximum reverse voltage
- Forward current and recommended series resistor
- Cut-out diameter and bezel depth
- IP rating if installed outdoors or in washdown areas
- Lens colour and viewing angle for readable status at distance
Quick compatibility guidance and accessory bundles
Match a lamp to your supply: for a 5V microcontroller LED use a series resistor calculated by Ohm’s law (see formula). For higher-voltage panels, choose bezel-mounted indicators with appropriate insulation clearances. We pack common accessory bundles - bezel + gasket + retaining nut - and offer pre-wired LED indicators for rapid assembly.
Ohm’s law for LED resistor sizing: V_R = V_supply - V_forward. R = V_R / I_forward. Example: 5V supply, LED forward 2.0V, target I = 10mA -> R = (5 - 2)/0.01 = 300 ohms.
