Questions on Amber in headlights

[PaulE]

I bought some very tired headlights as I've decided I want to build a spare set of projector headlights after successfully disassembling one of mine to re-epoxy the projector lens into its shroud. The headlights I purchased have amber turn signals. After I got them I saw that the amber sections were two different colors. The driver side is more orange, and the passenger side is more yellow/amber. I'm just curious, were there two different color ambers in the headlights over the years or has one just faded a lot more. I didn't want to de-amber the lights for my project, so I just found another passenger side headlight with an orange turn signal that better matches the driver side. The picture of the 3 headlights shows the difference in color, the middle one is the one I bought to have a better match.



The passenger side headlight with the yellow/amber section also has something weird attached to the inner lens. It is a clear cylinder about an inch long, filled with a clear liquid and perpendicular to the inner lens. There is some dirt on the inside of the outer lens so it's possible that this light was previously opened up. Just curious has anyone ever seen this on a Boxster headlight? Here are a couple of pictures of this thing.
