Description / 12v 5mm Flat Top Pre-Wired UV / Purple LED - Ultra Bright (10v, 11v, 12v, 13v, 14v, 15v)

The 5mm 12V Pre-Wired UV Purple LED ships ready to install with Approximately 15cm (6 inches) leads and a built-in current-limiting resistor. Connect directly to model railroad 12V accessory bus, automotive 12V system, RV house battery, marine 12V bus, or 12V DC power supply — no resistor calculation and no extra components needed. A uv purple led for model railroad lighting, automotive projects, and 12v panel indicators.

The 5mm (T-1¾) head is the most popular standard DIP size. Fits all standard 5mm LED holders, bezels, and panel-mount clips. Versatile for model railroad structures, automotive, RC vehicles, and panel indicators.

ResistorBuilt-in — no external resistor needed

Designed for

  • Model railroad layouts: Wire directly to your 12V accessory bus — no resistor math, no external components. 5mm head works at HO (1:87) and O (1:48) scale. DCC and DC layouts alike.
  • Automotive and motorcycle: Dashboard indicator relamp, footwell accent, instrument cluster backlight — connects directly to 12V vehicle electrical.
  • RV and camper van: Dome light accent, reading light, porch light indicator — runs directly off your 12V house battery with no extra wiring.
  • Marine and boat: Panel indicators for bilge pump, battery switch, and blower status. Note: these LEDs are not waterproof — mount in a protected location or inside a sealed enclosure.
  • RC crawlers and scale vehicles: Headlights, taillights, and turn signals for Traxxas TRX-4, Axial SCX10, and 1/10 scale truck bodies. Direct-compatible with 7.2V–14.8V LiPo packs.
  • Arcade cabinets and pinball: Illuminated pushbuttons (Sanwa/Seimitsu) from JAMMA 12V supply. Also backbox and playfield accent lighting for pinball restorations.

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).

About true UV LEDs: This LED emits genuine ultraviolet light at 395–405nm. To the human eye, true UV often appears as a deep blue or blue-violet hue rather than a vivid purple — this is normal and expected. The perceived color can change depending on what the UV light is shining on (fluorescent materials will glow brightly) and the ambient lighting in the room. In a dark room, the LED looks blue-violet; in a lit room it may appear dimmer than other colors because most of the output is in the invisible UV spectrum. True UV LEDs also have lower visible light intensity than other colors — this is inherent to the wavelength, not a defect. If you want a visibly bright purple without UV properties, see our diffused purple LEDs.
