Honestly it just reminds me of the moral panic over "cock ring Ken."

(also amusing in this context to note that his earring is in his left ear, so I'm not sure even the homophobes were consistent about this)
I believe they were already required to use reflectors. Back in the 80's when I was sometimes in Ohio with my parents we used to pass Amish buggies sometimes, and they always had an orange triangle retroreflector thing on the back.
