Light Up Your HO Scale World with These New Street Lamps
New Cornerstone Series Built-ups HO street lamps make adding realistic lighting to your scenes quick and easy. Each fully assembled lamp is made of durable metal and plastic to withstand layout service, and a unique socket mount on most models makes them easy to add to new or existing scenes. Installation is easy -- simply drill a mounting hole, insert the pre-wired socket, attach its wires to your power pack accessory terminals and plug the lamp in the socket. The universal sockets accept all of the socket-style lamps; platform lights and wall-mount lamps come prewired for permanent mounting and do not include a socket. An optional manhole cover is included with each socket-style lamp so sockets can be covered when necessary.
