Description / 3mm 9v Pre-Wired Cool / Clear White LED - Ultra Bright (7v, 8v, 9v)

The 3mm 9V Pre-Wired Cool White LED ships ready to install with Approximately 15cm (6 inches) leads and a built-in current-limiting resistor. Connect directly to standard 9V battery (snap connector), guitar pedal 9V supply, or any 7–9V DC source — no resistor calculation and no extra components needed. A cool white led for guitar pedal indicators, portable dioramas, and 9v battery-powered projects.

The 3mm (T-1) head is the smallest standard DIP size — scales realistically at HO (1:87) and N (1:160) scale. Small enough to hide inside model structures, dollhouses, and tight enclosures. Fits all standard 3mm LED holders and bezels.

Designed for

  • Guitar pedal status indicator: Standard 9V pedal power means this LED connects directly to your circuit — no resistor, no regulator. Works with Boss, MXR, EHX, and all DIY stompbox builds. Visible from a standing position looking down at your pedalboard.
  • Portable dioramas and displays: Single 9V battery powers the display for hours. Military dioramas, architectural models, and scale scenes at shows and competitions.
  • Cosplay and wearable props: A 9V battery is small enough to hide inside armor, helmets, and weapon props. Pre-wired means no soldering to tiny resistor leads — just connect and go.
  • Science fair and school projects: Safe, low-voltage, plug-and-play LED that works with a single 9V battery. No resistor math — perfect for students learning circuits for the first time.
  • Hobby electronics enclosures: Power indicator for any project box, pedal, or instrument running on a 9V snap connector or wall adapter.

Wiring

Red wire = positive (+). Black wire = negative (−). Reversing the wires will not damage the LED, but it will not light. Factory leads are Approximately 15cm (6 inches) leads with heat-shrink protected joints. For wiring tips, extending leads, and connecting multiple LEDs, see our Pre-Wired LED Voltage Guide.

Which voltage do I need?

Not sure which voltage tier matches your power source? See our complete Pre-Wired LED Voltage Guide — covers automotive, model railroad, USB, Arduino, Christmas village, guitar pedal, and battery-powered projects with a quick-reference table.

Department 56 village accessories use 2.5–3V adapters, which are below the operating range of these pre-wired LEDs.

Frequently Asked Questions

Yes — wire them in parallel (positive to positive, negative to negative). Each LED has its own built-in resistor. Do not wire them in series (daisy-chain), as the voltage drops will compound.
Strip 1/4 inch of insulation, twist matching wires (red to red, black to black), solder, and cover with heat-shrink tubing. Use 24-26 AWG stranded hookup wire for extensions.
Not directly — DCC track power is modified AC, not DC. Connect pre-wired LEDs to the 12V DC accessory bus instead. If you must use track power, add a bridge rectifier and smoothing capacitor first.

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.

Sold individually (1 LED per quantity ordered).
