Right you are yet again, Joe. Thanks for backing me up
with your usual common sense and knowledge of boating
related issues.

I tried to tell that ignorant putz, JR, the same thing but he
is too smug and self-absorbed to listen to the facts.

the manufacturers and dealers call them lens.


They do that so they can charge suckers more.

It is not a lens. A lens is a transparent optical device used to
converge or diverge transmitted light and to form images.

Hope this helps
