This is a bit of a departure for me in that it is rare to go this far back in time. It is a video sponsored by Chevrolet in 1940 and it is essentially selling the 'NEW" light technology. But what I found interesting is the discussion about ultraviolet and infrared light that was just on the cutting edge of technology. What you will find is the the fact that there are corrections to be made based on a look in the rear view mirror but still entertaining. It is also politically incorrect but not for 1940. Sometimes a look back gives us an appreciation for what seems new and relevant. The video is from the Prelinger Video Archive and is in the public domain. Enjoy a look at the past!
