Hi: I have a really nice condition 93 headlight. This set probably has the least amount of chrome pitting I have ever seen. The brackets are also pretty much rust free.
However, the passenger side headlight has one spot where the glass seems to be chipped on the INSIDE. From outside it is smooth.
I circled this spot in the picture, and as expected, it is not easy to take a picture of glass. IMO, it is not at all obvious.
The chip is not spreading from what I can tell. It has been exactly like that for about 3-4 years that I have had this headlight.
Here are some pictures:
Please let me know if you're interested, and thank you for looking.
