Lighthouse LEDs has been providing top quality components for over 20 years and have become the go-to supplier for many industries through Ebay and our personal website, where there is more ordering flexibility and products offered. If you need resistors, wire, heatshrink, switches or LED drivers you can find them at those links. We have, perhaps, the best and widest selection of LEDs out there!
10 x 12v 5mm Cube Frosted Lens LED - Red LED - Ultra Bright (5v-15v)

These red 5mm cube LEDs run directly on 12V without any external resistor — built-in current limiting means you connect them straight to your vehicle, boat, or model power supply and they work.

Each LED operates across a wide 5–15V DC range at 20mA, with a 620–630nm red wavelength, 5mm body, 22.5-degree focused viewing angle, and a milky white frosted lens that diffuses the light evenly rather than producing a harsh hotspot. Brightness runs 8,000–10,000 mcd — vivid red output visible in daylight.

Common applications

The focused beam and true red wavelength make these especially well-suited for night-vision-safe lighting, indicator lights, and accent work where red is functional rather than just cosmetic:

  • Marine night navigation: Sailboat and powerboat cabin reading lights — red preserves night vision while underway; direct 12V fit for most helm and cabin wiring
  • RC crawlers and scale trucks: Taillight and brake light builds on Axial SCX10 II/III and Traxxas TRX-4; 5mm fits most RC light buckets directly
  • Model railroading: HO and N scale block signal heads, grade crossing flashers, building interior warning lights — 9–15V track power compatible
  • Semi truck cab accents: Instrument cluster surround lighting on Peterbilt 379/389 and Kenworth W900 sleeper cab builds
  • CB and ham radio meter backlighting: Replacement for burned-out incandescent S-meter lamps in Cobra 29, Uniden Bearcat 880, and Kenwood TS-440 panel boards
  • RV and camper indicator lights: Panel warning lights, switch indicators, and bunk accent lighting on 12V coach wiring

Wiring & power notes

DC power recommended: LEDs are designed for DC. Running on AC will cause flickering and reduce lifespan. If using a low-voltage AC source (model railroad transformer, DCC track voltage), convert it to DC with a MB1S bridge rectifier plus a 100µF 50V electrolytic capacitor for clean, ripple-free output.

Building with this LED

Need supporting components? We carry a few staples that pair directly with this LED:

  • Thin lead-extension wire: 30 AWG Kynar wire — solid core, Teflon jacket, perfect for extending LED leads in tight spaces.
  • Hookup wire for power runs: 26 AWG Kynar wire — thicker conductor for supply rails and longer runs without voltage drop.
  • Bare tinned bus bar: 24 AWG tinned copper — solid core bare wire for bus-bar power distribution on perfboard builds and LED arrays.

Quality LEDs made in the USA since 2005.

Most of the times the postage on our items are free, but when it is not we do our best to make sure that you pay very close to the actual postage price. If you feel this is not the case on items that are not "Free Shipping" then please let us know and we will make the adjustment before you pay.

Again, this is such a rare instance we can nearly guarantee this won't apply to you. We ship the items as fast as we possibly can and via the methods stated, after that we have no say in what the postal system does with it. If they go beyond the estimated delivery time, it is not our fault. Please give us a break regarding this. Email us if you feel your item should have been delivered and isn't.
