Jonathanwilson on our forums has stopped by a couple times lately to show off some lighting kits. The first was the Hotel Corner lighting kit, and the second (which I find more interesting) is the kit for the Mercedes-Benz Arocs. The second kit is designed to work with technic elements, which is typically better for BIONICLE® MOCs. Another notable improvement is the addition of power cables for the lights which can connect to newer LEGO power functions battery boxes.
