12v 3mm Flat Top Pre-Wired Pink LED - Ultra Bright (10v, 11v, 12v, 13v, 14v, 15v)

The 3mm 12V Pre-Wired Pink 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 pink led for model railroad lighting, automotive projects, and 12v panel indicators.

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

• Model railroad layouts: Wire directly to your 12V accessory bus — no resistor math, no external components. 3mm head works at HO (1:87) and N (1:160) 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.

Complete your project

• Hook-up wire — extend your leads with 24–26 AWG stranded wire, splice with solder + heat shrink
• Switches — toggle, rocker, and mini slide for on/off control
• Power supplies — wall adapters and battery holders for your voltage
• 3mm LED Holders / Bezels — snap-in panel-mount clips
• Heat shrink tubing — protect extended wire joints

Sold individually (1 LED per quantity ordered).
