WOULD IT BE A SIN

Yes
I kind of imagined that the DOT mandated side markers for 68, and most manufacturers put lights in. Then they came back and said no they must be reflective, so the manufacturers put reflectors in for 69, and then the DOT came back and said no they must be lights AND reflective.

May not be that way, but that’s always been my theory.
Oh, and just to be a smart ***, lights usually are lit. (Well, as long as the switch is on, anyway)
I don’t know how to make the little pokey thingy
