A pack of 4 x finely scaled single-head (Sylvania light module) station, carpark or road lamps. Single lamps are often used on platforms with greater security/communication so two lamps also have an adjustable CCTV/speaker. Height adjustable. LED powered (Modern white light) lamps. The lamp posts are made from medical grade stainless steel tubing. Bases are ABS and feature all detail. Light control PCBs are included. Connection instructions on rear of each pack, with a PDF 'tips' file also available online. Designed and created to 4mm scale (OO/EM/P4) however lamp heads can vary in size in the real world and scale differences are very small. They look fantastic on HO layouts.
