Back-up (reverse) Lights Heads-up for Early A's (FYI)

I just read on another thread that the '65 Barracuda and '65 Valiant have different circuits in their respective headlamp switches. I'm not positive, but I believe the front parking lights turn off with the Barracuda when the headlamp switch is pulled all the way out.

I looked up both '65 Valiant and '65 Barracuda on Summit website and the same 3 headlamp switches were offered for both models: DS165, DS165T, and OER MD9341.

My '65 Formula S switch has Mopar 2580463.
