Headlight Switch

Posted by dienes83646 On 2011/1/26 9:29:32

I have a 1938 Packard, 1601 Series, 4-dr, straight 8. My questions concern the headlight switch.

What is the purpose of the thermostatic relay on the switch?

Also, are there 2, 3, or 4 positions on the switch? Mine is froze up and I'm considering using a universal switch in its place.

Any info would be helpful.
