As in 305 614 007...

I think I bought a pair of H1s just sort out once and for all in my mind the minutia of Porsche 911 Headlamp details.

And that is what is happening. I bought quickly a 'pair' of lamps because the price looked good if not cheap and the reflectors displayed well in photos taken through the clear glass on top.

I did not notice difference in fluting until I took them apart. The entire lamps are different and one is obviously older. So I went through the lamps, put them on my '67 and posted images here. That is the best way to find out definitively that they came out first on 68 row cars. Bosch says they came out in 66 - but they don't say they were on a Porsche Three concerned citizens have pointed out to me that 1) they don't belong on the car and that 2) one of those lamps is harder to come by.

I love it here. Now I'd like to find another incorrect lens for my car

PM please if yi has one.
