I've been working on my school bus conversion for a while now. All the lights on the inside where changed to LEDs. While I changed all the exterior light fixtures I replaced them with modern incandescent lights. Exterior LED truck/bus lights were not as readily available then as they are now. My old round headlights are dim and out of style. While working the Sugar Beet Harvest in North Dakota I noticed several new trucks with round LED headlights come through the un-loader. Hence, the search was on. Below are the results.
