Mercury lights

[1stford]

Have 2 questions around the lights on my Mercury, 12 volt.

1). Should the running lights, lights on top
of the fenders, be on when my headlights are on?
*Currently they come on when the switch is pulled half way out*

2). Where is the best place to buy a new head light for that car. My high beam is out. My light says “made in USA” on the bottom of it.

Thanks.
