Add extra 600 ohm resistor to green light to balance brightness. - These are cute little additions to add to any HO or N gauge train layout and if you add block or infrared sensors are even more engaugeing. ## Features - 100% Brand new and high quality.Perfect for Railway & Building Layout!Great accessories for diorama, buildings, train models. - Prewired quality products.Lights include red and green leds.Each line corresponds to the color of the glowing colors, the green line is the green LED, the red line is the red LED.Black wire with positive, and the other two with negative. - You must connect a resistor in series before you will use them on 12V or 16V, I will supply compatible resistors for free. - Reference Scale: 1:87,Suitable for HO scale.Operating Voltage: 12V, AC or DC Compatible.Operating Current: 20mA.Material: Plastic - Package included: 3 complete lamps,including 3 Resistors for 9~18V operation. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07DW5BFW9 | | Customer Reviews | 4.1 4.1 out of 5 stars (56) | | Is Discontinued By Manufacturer | No | | Item Weight | 0.64 ounces | | Item model number | JTD873GR | | Manufacturer | Evemodel | | Manufacturer recommended age | 14 years and up | | Product Dimensions | 3.6 x 2.5 x 0.6 inches | ## Images ![JTD873GR 3PCS Model Railroad Train Signals 2-Lights Block Signal HO Scale 12V Green-Red Traffic Lights for Train Layout New - Image 1](https://m.media-amazon.com/images/I/51lDjqqD09L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works well with Raspberry Pi *by D***N on August 11, 2024* Hooked these up to a RPi with a shift register and Darlington array. Works great with a little programming effort. Will add great visuals to the layout ### ⭐⭐⭐⭐⭐ Easy to hook up. Add extra 600 ohm resistor to green light to balance brightness. *by B***G on October 24, 2018* These are cute little additions to add to any HO or N gauge train layout and if you add block or infrared sensors are even more engaugeing. ### ⭐⭐⭐ Good value, but connecting wires are way too thin. *by S***. on September 21, 2025* It's good value. They work well with any Voltage in the range 3V to 12V. But what's with the super super thin single strand wire? A simple mishap and your signal light is gone! I have to solder some thicker multi-strand wire just to protect the single strand wires from breaking. ## Frequently Bought Together - JTD873GR 3PCS Model Railroad Train Signals 2-Lights Block Signal HO Scale 12V Green-Red Traffic Lights for Train Layout New - JTD876RP 1 Set HO Scale Railroad Train/Track Crossing Sign 4 Heads LED Made + Circuit Board Flasher-Flashing Red Train Signal Lights Decoration and Party - JTD873GYR 3PCS Model Railroad Train Signals 3-Lights Block Signal HO Scale 12V Green-Yellow-Red Traffic Lights for Train Layout New --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/77352594-jtd873gr-3pcs-model-railroad-train-signals-2-lights-block-signal](https://www.desertcart.us/products/77352594-jtd873gr-3pcs-model-railroad-train-signals-2-lights-block-signal) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-18*
