While driving through "Pennsylvania Dutch" country yesterday evening, we noticed that many of the traditional Amish buggies are now outfit with LED cluster bulbs. They're quite a bit more visible than the conventional types, and probably make the battery last much longer as well: safer for the long journey. Now all they need is a solar panel on the buggy roof. We auto drivers may find such the perfect transportation after the tail of the Peak Oil curve. Photo credit: LED Lights.
