I remember seeing quite a few neon colors on sunglasses and windshield wipers in those days. I was doing quite a bit of surfing in NH and Maine at the time and most the younger guys were wearing Body Glove wetsuits with similar colors. A couple of years ago, a co-worker found out that I surfed, and insisted that I take a wetsuit that he bought but didn't use - day-glow pink and green!
I don't recall seeing the trend on bikes, and the 88 Cannondale that I bought new was all black.
