Description / 3mm Round Top Red LED - Ultra Bright
The 3mm Red LED (Round Top, Clear) is the standard through-hole LED for power-on indicators, brake/tail light accents, model railroad stop signals, alarm and fault LEDs. 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.

- Power-on and status indicators: The universal "on" signal. Breadboard prototyping, enclosure builds, equipment panels.
- Model railroad signals: Block signal stop aspect, grade crossing heads, yard limit indicators. Clear lens for focused, directional signal visibility.
- Automotive accent: Brake indicator, taillight accent, dashboard warning LED relamp. 12V with appropriate resistor.
- Christmas light replacement: Replace burnt-out C7/C9 string light bulbs with LEDs — cooler running, longer lasting.
- Guitar pedal indicator: Red is the standard "effect active" color across all DIY stompbox communities.
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.
