71 72 73 Dart Tail light lens trim

TrailBeast said
I own a 73 dart and the bumper is the only metal trim around the lenses.
There is no part that you could burn the plastic out of involved anywhere in or around the lenses.

May be I'm missing something?

Not all the Dart tail lamp lenses had this metal surround on the inner part of the lens.Most are just painted silver.
