Add realistic detail to the end of your model train! This is a ready-to-run, pre-built flashing EOT/FRED kit in N scale. EOT/FRED stands for End-of-Train device or Flashing Rear End Device - it's the little red light that flashes on the back of real freight trains. This one from Big Windy has a bright red LED and is powered by a common 3-volt CR1220 battery (not included). The MPN is BNFO8051220WS. It's brand new, mint condition (C-10 grading), and made in the United States. The scale is N, and the gauge is N. It features a light function and is controlled via analog systems. It's recommended for ages 14 and up. This isn't a DIY project; it's a complete, assembled unit. Just add the battery, mount it on your caboose or last car, and you've got an awesome, authentic flashing tail light. It's a small detail that makes a huge difference in the realism of your layout. The red light is nice and crisp. Perfect for modern-era freight train models. UPC doesn't apply. If you want your railroad to look legit, this is a must-have accessory.

It's tiny, well-made, and works great. The installation is simple. Watching that little red light flash as your train rolls through the scenery is super satisfying. A top-notch detail part for serious modelers.
