Saw a display of LED tail lights at a show that included the ones we have on the 47-53 Chevy trucks. They were just on a wooden panel and illuminated. However when I was looking at them the salesman turned a switch and said this is how they look when you put on the brakes. I almost went blind! So bright! I started to wonder if in fact they are that bright or did he have some sort of super dynamo hidden behind that panel. They were very impressive and I am tempted.
