Automatic Dimmer Switch?

[Stepside Jim]

Hi everyone, I'm deep into the wiring of my '57. I have a floor mounted dimmer switch which I would like to use it for another purpose other than a dimmer switch for the headlights.

If I'm not mistaken wasn't there a option on luxury cars back in the '60s or '70s that had a sensor somewhere in the grill that would sense oncoming vehicles and would automatically dim your headlights for you?

As I've been taking care of the wiring I had it in the back of my mind that I would just Google and order this automatic dimmer but I don't seem to find it anywhere.

Perhaps I'm not using the right terminology in my search, anybody heard of such an item in the aftermarket? Thanks, Jim
