What a shame. I remember as a child asking what kind of lights were on the aircraft we often watched, this was the sixties. My friend's Dad was very knowledgeable in this arena and answered those are strobe lights by Whelen and they're ONLY approved for aircraft usage. Two+ decades later,... we had some of the first Edges in the early eighties on our wreckers. Special ordered fully loaded strobe bars with work lights to rear. I think they were actually about 2K in cost, so I was told. Those strobes were great for business, often as we were cleaning up one wreck two more would happen from hypnotized rubberneckers. Progress aye? Jump aboard or get run over. Can't help but wonder what will come along one day to trump the LEDs.
