Brawa N Scale LED Street Lights and other layout lights are easy to add to any layout or diorama. Each plug-in light includes spring-loaded sockets that are resistant to shock and can bend slightly to resist damage from handling. Parts are combined brass and plastic for great realism. The pin-socket system allows you to change or replace lights in minutes without complex wiring changes. Worry-free LEDs mean they will last for years without requiring bulb changes.
