Description / 5mm 12v Pre-wired Flashing Blue LED - Ultra Bright

The 5mm 12V Pre-Wired Blue SMD LED comes ready to install — pre-wired leads, built-in current-limiting resistor, 5mm SMD package. Connect directly to 12V DC with no resistor math or extra components.

Self-blinking: blinks automatically at ~1Hz — no oscillator or controller needed. Same wiring as a static pre-wired LED.

Size5mm
Operating Voltage12v (volts)
LED Forward Voltage12v (volts)
Brightness12,000-14,000mcd
Wire Lengthpre-wired leads
ColorBlue
ResistorBuilt-in — no external resistor needed

Designed for:

  • automotive (car, truck, motorcycle), RV, boat, and van build
  • Arduino indicator and circuit board status LED
  • Fits all standard 5mm LED holders, panel bezels, and dashboard clips
  • Polarity: red wire = positive (+), black wire = negative (−)

DC power required: Animated LEDs (flashing, flickering, fading) require DC — they will not operate correctly on AC power. If you're working from a low-voltage AC source such as a model railroad transformer or DCC output, you must convert to DC first using a bridge rectifier.
