I’m not sure if this poll has been taken yet, but I tried finding one and I couldn’t. The Porsche 911 was not originally designed to have the US DOT Headlights. That being said, they are correct for all 1968-1973 cars. Living in the US with a US market car, do you make the switch or do you keep it original? Just for fun assume you have both sets of lights already and cost is not an object.
