Lego Fiber Optic 1996 In the early 2000s, LEGO was close to bankruptcy with poor management and runaway costs. An example of this was LEGO Technic Fiber Optic, which featured specialized parts with LED lights. Transparent plastic tubes were connected to a battery pack so that light showed through the plastic. According to LEGO designer Mark Stafford, “It cost LEGO more to source these parts than the price whole set was being sold for - every one of these sets was a massive loss leader and no one actually knew it.”
