The units reportedly deliver just the right amount of heat and illumination to encourage the growth of the cannabis plants, while using little in the way of electricity, making them a favorite among the narcotic cultivators. Rather than buy the $700 units from a parts supplier, though, the pot growers have been running around the Netherlands stealing them (with apparent ease) off parked Panameras and Cayennes, leaving the luxury vehicles without their headlights (along with an apparent lack of alarm systems). Now put that in your pipe and smoke it. (Disclaimer: CarBuzz is not advocating putting anything in any pipe or smoking.) Photos courtesy of Autojunk.nl.
