Ok, an update! So yes, the Lumina's have this feature. A gentleman on FB has a beautiful 92 Z34 5 speed car and his illuminated door lock still works. He sent me this pic. The only question now...is his partially burnt out? Only the bottom part of the ring is lighting up. Isn't the entire ring suppose to illuminate? So we know the Lumina and the Cutlass have a green light. I wonder if the GP and Regal use a different color?
