I asked on twitter if anyone knew of any other cars that used these rear lights and Colin Mee came up with the following…

This is a Lola Mk6 GT Chevrolet and the image comes from the ultimatecarpage.com. Thanks, Colin!

EDIT 20 FEB 2018

I’ve found another one! Here’s an Australian Cortina 440 Fastback. Not the prettiest car I’ve ever seen but I do like the lights! For more information see Wikipedia.
