Description / 3mm 12v Pre-Wired Ultra Bright LED - RGB Fast Auto Change 6v 7v 8v 9v 10v 11v

The 3mm 12V Pre-Wired Red/Green/Blue (RGB) SMD LED comes ready to install — pre-wired leads, built-in current-limiting resistor, 3mm 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.

Size3mm
Operating Voltage6v-12v
LED Forward Voltage6v-12v
Brightness5,000-8,000mcd
Wire Lengthpre-wired leads
ColorRed/Green/Blue (RGB)
ResistorBuilt-in — no external resistor needed

Designed for:

  • automotive (car, truck, motorcycle), RV, boat, and van build
  • color-changing RGB indicator — red
  • Fits all standard 3mm 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.
