Description / 3mm Round Top Amber / Orange LED - Ultra Bright

The 3mm Amber/Orange LED (Round Top, Clear) is the standard through-hole LED for automotive turn signal. Clear lens with a focused 20-30 Degrees beam — bright and directional, the classic DIP LED that fits every breadboard, panel bezel, and holder on the market.

The 3mm (T-1) head is the compact choice — fits smaller enclosures, 1590A/1590B pedal boxes, and scales realistically for HO and N gauge model railroad signals and indicator positions.

Forward Voltage1.9-2.1v
Brightness9,000-10,000mcd
Viewing Angle20-30 Degrees
LensClear — focused beam
PackageT-1 through-hole DIP

Common applications

  • Hobby electronics: Amber/Orange indicator for Arduino, breadboard prototyping, and enclosure builds.
  • Model railroad and scale models: Signal lighting, accent, and scene illumination.
  • Automotive accent: Dashboard indicator, footwell glow, interior accent with appropriate resistor.
  • Cosplay and props: Accent lighting for costumes, weapons, and display pieces.
  • Holiday decorations: Custom color accent for seasonal displays and light projects.

Standard T-1 through-hole footprint. Fits all 3mm LED holders, bezels, and panel-mount clips. Add a current-limiting resistor matched to your supply voltage — see our LED Resistor Calculator for the exact value.

Need a wider beam? See our 3mm Diffused Round Top LEDs (soft glow, no hotspot) or Diffused LEDs for soft glow applications.

Frequently Asked Questions

Yes. Standard LEDs require a current-limiting resistor matched to your power supply voltage. Use our LED Resistor Calculator at /blog/led-resistor-calculator.html to find the exact value.
Clear lens LEDs produce a focused, directional beam (15-30 degrees) — bright when viewed head-on. Diffused lens LEDs scatter light evenly for a soft glow visible from all angles. Use clear for signals and indicators; use diffused for ambient lighting and props where the LED is visible.
Yes. Connect through a current-limiting resistor (typically 220-330 ohm for 5V) to any digital output pin. The LED Resistor Calculator can help you find the exact value for your setup.

DC power recommended: LEDs are designed for DC. Running on AC will cause flickering and reduce lifespan. If you're using a low-voltage AC source — such as a model railroad transformer output or DCC track voltage — convert it to DC first with a bridge rectifier.
