Not to change the year but again red in color

I always found this interesting and without an explanation from anyone - I have seen more then a few of these over the years - The horizontal stripe down the middle of 71 charger concealed headlamps - Most are black some gray/silver in color but - Trust me when i say my 71 Superbee concealed headlamps have never been restored - Yes there coded on the broadcast sheet/fender tag but the red in color - Anyways
