The description says "UV treated polycarbonate" which typically means once the coating is blasted off by road grit the underlying plastic will start to yellow and fade. I wish they were glass as well.

Those Holley lenses look great. I'm tempted but I want someone else to do it first.... haha. I'd definitely get them PPF'ed.

I really enjoyed this write-up and this was the very first thing I did to my car a couple of years ago. That said, the cheap glass casings on Amazon are not good in my opinion. They scatter the light so much that they are impossible to aim without blinding oncoming traffic. The LEDs I happened to buy on Amazon as well had a similar issue. Putting both together, my headlights were basically floodlights.
I purchased a headlight kit from Chris Miles which was Hella housings and Morimoto LEDs. They give a much much better cutoff, similar to any other modern car I have driven. Attached are some comparison pictures in my garage at a distance of about 4 feet from headlights to white backdrop.

I used the cheap glass housings and forgot which LED I got. Later I bought one Hella housing and my comparison found no difference. Maybe the LED is the controlling factor.

Thanks for sharing, that's another helpful data point. In the pictures above, I did try all combinations of LED and housing that I had. It looked to me like the housing was more important than the LED, but both did seem to matter. From what I can tell as well, the low beam "shutters" on the LEDs do vary across all of them, so it may depend on specific model. The Morimoto shutter does seem to be the most round and reflective, so it makes me think they are putting a bit more into the engineering than the cheaper LEDs.
