When did parking lights stay on with headlights?

As the title states, what year did the Chargers parking lights still stay on when you turned on the headlights?

(from the factory, not retrofitted like I did with my 66's)

Thought it was '69?

I'm not sure, which is why I asked..... my 70 parking lights stay on with headlights.

I got a keyboard warrior trying to tell me that his 66's stayed on with the headlights as well, I told him that the car didn't come that way from the factory.

I changed the front parking lights to stay on with headlights on in my cars

69 was the first year. It was done just adding a jumper wire to the harness able to feed the front circuit from the rear circuit, and this made able to keep the same switch from earlier years
