Hey there model train enthusiasts! Check out these awesome 5-piece street light sets that'll really bring your railway layout to life. These aren't your average lampposts - they feature warm white LEDs and double heads that give off just the right amount of glow. Standing at 65mm tall (that's about 2.56 inches for those who prefer imperial), they're perfectly scaled for HO gauge layouts at 1:87 ratio. Now here's the important part - these babies run on 3V only, so don't go plugging them directly into your 12V or 16V tracks unless you want fried LEDs! The good news is we include free resistors (not pre-soldered) so you can safely use them with higher voltage systems. Made with solid coppery columns, these lamps come ready to install with wires and LEDs included. They're super easy to set up and will make your miniature town look absolutely stunning at night. Perfect for lining your streets, station areas, or anywhere you want that realistic urban feel. Just remember to keep that operating current at 20mA per LED for optimal performance. Your layout deserves these quality lights - trust me, you'll notice the difference immediately when you see how they illuminate your creation!
