Recently I purchased a new car and was amazed at how much technology is packed into it. From radar cruise control and self steering, to blind spot monitoring and collision avoidance its great to see how far we have come since the advancement of the micro processor. One item that caught my eye is the fact their is not a single Edison light bulb in the car. It is 100% LED technology even the Headlights!

You had your choice of acetylene or oil and the Prest-O-Light company had a great storage and delivery system for the acetylene gas.
