Product Overview
5mm Through-Hole Auto-Flashing RGB LED - 2-Pin Self-Contained Color Cycler, 3.0-3.4VDC
Condition
Unused NOS. Functionally tested. Leads are straight and unkinked, frosted dome lens is clean and unscratched, no oxidation on pins. No inclusions beyond the LED itself - a current-limiting resistor is not included and is required for safe operation.
Ships same business day from Idaho. Packed carefully.
Backed by our guarantee.
Product Overview
5mm round through-hole RGB LED with a frosted dome lens and 2-pin connection. Internal control circuitry handles all color cycling automatically - no microcontroller or external driver required. Connect power and it runs. Forward voltage 3.0-3.4VDC.
Key Features
- 5mm round through-hole form factor
- 2-pin connection - anode and cathode only, no separate color channels
- Built-in auto-flashing IC - cycles red, green, blue, and combinations automatically
- Forward voltage: 3.0-3.4VDC
- Frosted dome lens - confirmed by photo inspection
- Max forward current: approximately 20mA - Not confirmed for this specific unit, verify before use
- Leads straight, unkinked, and free of oxidation
Applications
- Status indicators and decorative blinkers in DIY enclosures
- Prop and costume builds where plug-and-play color motion is needed
- Beginner electronics projects - no driver code required
- Throwies, LED art installations, and maker light shows
- Breadboard prototyping for simple color-effect circuits
Frequently Asked Questions
Do I need a resistor with this LED?
Yes. A current-limiting resistor is required to prevent burnout. Calculate the resistor value based on your supply voltage and a target current of approximately 20mA. The LED is not included with a resistor.
Can I control which color is displayed or when it flashes?
No. The flashing sequence and color cycling are handled by internal circuitry. There is no external access to individual color channels. If you need per-channel control, you need a 4-pin RGB LED and a driver circuit.
Is the lens frosted or clear?
Frosted. Photo inspection of the specific units confirms a frosted dome lens. Frosted lenses blend colors internally and produce a wider viewing angle than clear-lens versions.
What voltage does this run on?
3.0-3.4VDC is the rated forward voltage. Operation at higher supply voltages is possible with an appropriate current-limiting resistor - verify the resistor value for your circuit before use.
Two pins, one job: light up and move. This little LED does the whole color show on its own - no code, no controller, just power and a resistor. Plug it in and see what it does.
