This simulator is designed to reproduce those intermittent sparks of varying intensity for either two outputs (for dual pantograph applications) or a single output, for one pickup like many early-era trolleys had. The tiny size of Ngineering Nano white LEDs is perfect for this application.\u003c\/span\u003e\u003c\/p\u003e","brand":"Ngineering","offers":[{"title":"Default Title","offer_id":45827699343558,"sku":"N-8063","price":13.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0619\/2205\/0246\/files\/LightDimDNI.jpg?v=1778965299","url":"https:\/\/railroadkits.com\/products\/structure-lighting-simulator-controller-module-copy","provider":"RailroadKits \u0026 Microlumina","version":"1.0","type":"link"}
