Model railroaders, these HO scale lamp posts will totally bring your layout to life! Standing 5.8cm tall, they're the perfect size for 1:87 scale scenes and add that realistic touch of street lighting to your towns and stations. The warm white LEDs give off just the right amount of light - not too bright but enough to actually illuminate your scenes. Now important note - these run on 3V, so you can't just plug them directly into 12V or you'll fry the LEDs. But they include resistors in the package, so with a little basic wiring you can hook them up to your layout's power supply. The construction feels solid with ABS and metal materials - way better than those flimsy plastic ones that break if you look at them wrong. Each package comes with 3 lamps and 3 resistors, so you can light up a good section of your layout. The wires are thin enough to hide easily, and the red/blue wiring makes polarity simple to figure out. Whether you're creating a city scene, train station, or just adding some atmosphere to your landscape, these lamps make everything look more realistic and detailed. Seriously, lighting is one of those things that takes your model railroad from good to amazing.
