Now aging myself a bit. The same service in had an old Miller Meteor 1972 Cadillac that was still licensed basic. Yes I took it on a call, but it was only a long-distance transfer. It had three huge beacons on the top, 3 sidelights on each side that sequenced front-to-rear, 2 sets of front tunnel lights-one was standard wig-wags, the other red and white Mars lights with the figure 8 pattern. For sound-how about a Federal Director through the two large rooftop speakers. Then just for fun, crank up the Q that was on the roof. That will rattle your fillings. Too bad it sucked so much power that when you wound it up all the lights in the back would go out and the beacons would dim and slow to a crawl until you let the Q coast.
