Here's a point to consider.... Many owners have had these bezels rechromed. I've never seen one comment about what effect all that chrome has on the lighting. We look at it and assume a lighting engineer went to a lot of trouble to control and level the light.
The metal rings were once raw metal, then painted both white and black. If all these strange markings were simply from their fixturing, why not all black? I think we assume correctly. Put it together as is and light it up?
If it comes to your wanting or needing another glove box script, I have plenty of them.
