Description / 5mm 12v Pre-Wired Cool / Clear White LED - Ultra Bright (10v, 11v, 12v, 13v, 14v, 15v)

The 5mm 12V Pre-Wired Cool White 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 cool white for modern commercial structure lighting on model railroad layouts, automotive dome lights, and panel indicators.

Cool white simulates fluorescent or modern LED lighting — the right choice for commercial buildings, gas stations, and industrial structures on model layouts.

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.

Size5mm (T-1 3/4)
Operating Voltage10V – 15V DC (10V, 11V, 12V, 13V, 14V, and 15V)
LED Forward Voltage10v-15v (volts) (15v Not Recommended Continuous)
Drive Current20mA typical
Brightness15,000-18,000mcd
Viewing Angle20-30 Degrees
WireApproximately 15cm (6 inches) leads, heat-shrink protected connections
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).

Review by Verified Buyer
Item arrived exactly as described and at a great price. Shipped quickly and arrived in just a few days. I Would buy from again. I wonder how these LED's would light if I were to connect an AC power cord from a disposed lamp? Would they light up? Sincerely, Mark A. Clay Sr. KD8FZH-WROW437 & WYLC RADIO
