You can choose whether you want to integrate the lighting after assembly or directly during construction, supported by 3D instructions. The new LMB 2.0 components have been completely redesigned: They offer the flattest and most stable cables of all manufacturers, which can be easily routed between LEGO bricks, as well as connectors that can be plugged in without alignment. Some LEDs already have integrated effects and many components are equipped with studs, making them easy to integrate into LEGO models. With LMB 2.0, models can be illuminated in a completely new way.
