5mm 12v Pre-wired Flickering / Candle Blue LED - Ultra Bright

The 5mm 12V Pre-Wired Flickering Blue LED has a built-in candle-flicker IC that randomly varies brightness to simulate a realistic flame — no controller, no programming, no microcontroller needed. This candle flicker LED connects directly to 12V DC and produces an organic, non-repeating flicker pattern on its own.

Ships ready to install with approximately 6" (15cm) pre-wired leads, a built-in current-limiting resistor, and heat-shrink protected connections. Connect directly to 10V – 15V DC — no resistor math, no extra components.

Blue flicker produces a ghostly, ethereal shimmer — used in theater for spirit and paranormal scenes (A Christmas Carol, Macbeth) and haunted house ghost effects.

How the flicker works: A tiny IC inside the LED randomly modulates current to produce a natural, non-repeating flicker pattern. Unlike PWM dimming or microcontroller code, the pattern never loops — each LED flickers independently. Place multiple flickering LEDs in the same scene and they will naturally drift out of sync, creating an organic, non-synchronized shimmer.

The 5mm head is the most popular size for candle and flame builds — fits standard 5mm LED holders and is the right scale for jack-o’-lanterns, candelabras, village buildings, and escape room torches.

Popular builds

• Halloween props: ghost and spirit theatrical effects, paranormal haunted house props, and icy magical glow. Replaces disposable battery tea lights with a wired, permanent installation. Each LED flickers independently — use 2–3 together for a convincing multi-flame effect.
• Model railroad and diorama fire scenes: sci-fi energy effects. 5mm head works at HO (1:87) and O (1:48) scale.
• Christmas village displays: Fireplace glow for Department 56 and Lemax buildings, German-style Schwibbogen candle arch tips, nativity scene lanterns.
• Theater and film props: Stage candelabras, period drama tavern sets, dungeon torch sconces. NFPA 160 prohibits real flames on stage — flickering LEDs in wax shells are the industry standard.
• Escape room props: Altar candle scenes, dungeon torch wall sconces, mystical artifact glow. Wire into your 12V prop bus for all-night operation.
• Flameless candle repair: Luminara, Homemory, Sterno Candle Lamp, and similar battery candles fail when the motor or circuit dies. A replacement flickering LED restores the effect at a fraction of the cost.

Pro tip: Blue flicker reads as supernatural or ghostly on stage and in props. Mix one blue with two orange/yellow for a gas-flame effect with a blue core.

Wiring

Red wire = positive (+). Black wire = negative (−). LEDs are polarity-sensitive — reversing the wires will not damage the LED, but it will not light.

Factory leads are approximately 6" (15cm) pre-wired leads of stranded wire with heat-shrink protected solder joints. To extend: strip ¼" of insulation, twist matching wires (red to red, black to black), solder, and cover with heat-shrink tubing.

Complete your build

• Hook-up wire — extend leads with 24–26 AWG stranded wire
• Switches — toggle or mini slide for on/off control
• Power supplies — wall adapters and battery holders
• Heat shrink tubing — protect extended wire joints
• 5mm LED Holders / Bezels — mount in panels and enclosures

Sold individually (1 LED per quantity ordered).
