Priced high at $8000 but looks like an exceptional example. https://minneapolis.craigslist.org/hnp/cto/5656948312.html
The car is nice but what do you do with a car like that? If you're going to have four doors you might as well step up and get a wagon. The seats look like they're made of the same blue velour material they used to make the tunics for TV's Star Trek?
No it was an Optional Quartz Light that supposedly did not blind on coming drivers but was brighter than High beams. Cost around $50 when new. Actually a lot of cash for the day. I had one on a Polara back in the 70's but it was burnt out, and I was to cheap to spend the $10 for a new bulb (I was about 17 at the time and would rather spend that on beer! or girls) I later found out it was illegal to use in Colorado at the time. Probably why the previous owner did not fix it.
Stands to reason I wouldn't have seen this as a kid; Mom and Dad never bought Mopar, nor did anyone I knew that I can think of. Only my brother Geoff had Mopar cars when he was driving--the Dog Fart, a '69 Dodge Dart with a Slant Six/three-on-the-tree, some Chrysler big boat with a non-functioning electric bench, and the previous owner was a Munchkin, and two Plymouth V6 minivans (both had the 3.3L). Very interesting how it was used to illuminate the right side, but Colorado banned it!
