1966 Bronco Running Lights Question

[NCSUWoj]

Got a 66 here I am putting the final touches on and just now getting all the wiring straightened back out. All original harness that does no have the first splice in it. Got running lights front and rear when the headlight switch is at the first level. Once I pull the switch all the way out for the headlights, my front running lights go out but the taillights stay lit. The question I have for you 66 owners is are my front running lights supposed to go out with the headlights on or do I have a problem? It seems strange that my taillights stay lit but the fronts go out when the headlights come on. It is a new headlight switch. Any thoughts?? PS My 74 the running lights stay lit all the way around with the headlights on.

That is the way they work.
Mater fact that is how all Fords worked up till the early 70s.

Had to do with the low power output of the generators.
When the altenators started putting out more and reliable power the park lights stayed on, along with the additions of other loads.

x3....my 66 still has the original harness and the parking lights go out when headlights are on

My 65 mustang was like that too
