I would love to see a video with sound while the beasts are being driven so that real world volume of the buzzer over the sounds of a driven truck can be determined. I really like the idea of a very simple and clean install but if it can't really be heard when operating the truck doesn't do me any good and I'll just run some wiring from the bulb socket to activate a piezo buzzer mounted to the steering column if need be. Wouldn't be as clean a install but for sure would be loud enough to hear.
