Yes, some interesting information. My car still has the inner/high beam General Electric ' MADE FOR FORD ' bulbs. Of the outer headlights; one had been replaced before I got the car and the other I just replaced. The replaced/burned out one was a TS ' MADE FOR ' bulb. You might add that a little Windex and a paper towel will take the ink stamps right off. When replacing the bulb I did not notice any stampings on the bucket ? Will have to look harder next time. The pictures of the bulb faces are really pretty good as the glass shots are pretty tuff. Thanks, Brian
