Model railroad enthusiasts, these Evemodel signal targets are exactly what you need to bring your layout to life with authentic railway signaling! Each pack comes with 10 complete signal heads featuring both green and red LEDs for that realistic two-aspect signaling. They're perfectly scaled for HO, OO, and TT gauge layouts (around 1:76 to 1:100 scale), so they'll look right at home on your model railway. Now, here's the important part - these come unsoldered, meaning you get to do the wiring yourself, which is actually great because it lets you customize the installation to fit your specific layout needs. The LEDs operate at 3V (AC or DC compatible), and they include free resistors for when you're running them on higher voltage systems like 12V or 16V - super important because connecting them directly to higher voltage will damage the LEDs. The plastic construction is detailed enough to look realistic but easy to paint if you want to customize the colors. Whether you're building a modern mainline, a vintage branch line, or anything in between, these signals add that professional touch that makes your layout stand out. They're one of those details that might seem small but actually makes a huge difference in how authentic your model railroad looks. Just take your time with the soldering, use those included resistors for higher voltage systems, and you'll have working signals that'll impress everyone who sees your layout!
