Tiny 2mm flat-top white diffused LEDs, pre-wired with 20cm leads and ready to use straight from the pack. The flat-top lens produces a wide, soft glow — ideal for tight spaces where a standard 3mm LED simply won’t fit. No soldering, no resistor maths — just connect to 5V and go.

How to Connect
Red wire → Positive (5V supply or GPIO pin)
Black wire → Ground (GND)
The resistor is already soldered inside the heat shrink near the LED — no additional components needed. Compatible with Arduino, Raspberry Pi, ESP32, and any regulated 5V supply.

Common Uses
Tight-space indicator lights where 3mm won’t fit
Scale model & diorama lighting — cockpits & detail work
Custom control panels & miniature enclosures
Breadboard prototyping & circuit learning
Arduino & microcontroller status indicators
RC models — nav lights, instrument panels & interiors
Common Questions
Do I need an external resistor?
No — the resistor is pre-installed inside the heat shrink tubing near the LED. Connect directly to 5V and GND.
Why choose 2mm over 3mm?
The 2mm flat-top form factor is ideal when space is very limited — panel cutouts, scale models, tight PCB layouts, or anywhere a standard 3mm dome won’t physically fit. The flat top also gives a slightly wider side-on glow.
Can I use these at 3.3V?
They will light up at 3.3V but will be noticeably dimmer. The built-in resistor is sized for 5V operation.
Please note: These LEDs are pre-wired for 5V DC only. Do not connect to 12V or mains power. Polarity matters — red wire is positive, black is negative. Sold individually.
