rocketraider Posted August 6, 2022 Share Posted August 6, 2022 Does anyone own or know of a 1960 Buick equipped with Twilight Sentinel? I have a Delco Radio training manual "1960 Delco Electronic- One Week Advanced Training School". It covers WonderBars, TransPortable radios, Delco garage door openers among other things. In the very back of the manual, there's an 8 page section on "Twilight Sentinel Automatic Lightswitch" subtitled "Service Instructions for 1960 Buick Model L460" applicable to all 1960 Buicks. Bulletin 6D-476 dated 10-15-59, 1st issue. I had always thought Cadillac was the first to get Twilight Sentinel but this manual belies that, since it includes only Guide-Matic repair section for 1960 Cadillacs.

Frank DuVal Posted August 10, 2022 Share Posted August 10, 2022 Curious, does that Twilight Sentinel turn lights on and off? Or dim lights? Here is something from 2016 which is NOT what Wikipedia says today! It is a few posts down the page, as the subject is selling a modern control: https://www.v8buick.com/index.php?threads/1-981467-nos-twilight-sentinel-very-rare.313166/ So, Wikipedia changed from Buick first to Cadillac first, 4 years later model year.

TexRiv_63 Posted August 10, 2022 Share Posted August 10, 2022 Both Twilight Sentinel and GuideMatic are listed in the owner's manual as options. Link to comment Share on other sites More sharing options...

rocketraider Posted August 10, 2022 Author Share Posted August 10, 2022 Turns driving lights on and off depending on available light. It does not incorporate headlight-off delay as later versions did. Appears to be completely separate from the Guide-Matic automatic headlight dimmer. I think I'd trust a GM-Delco service and training publication over Wikipedia.😉 Don, does the 1960 owner's manual have a picture of the TS "manual-automatic" switch? Training manual indicates it's located above and to left of the main lamp switch. Link to comment Share on other sites More sharing options...
Frank DuVal Posted August 11, 2022 Share Posted August 11, 2022 Well, Glenn, time for you to re-edit the Wiki! No, I do not know how either.....🤣 I love real manuals. Link to comment Share on other sites More sharing options...
rocketraider Posted August 11, 2022 Author Share Posted August 11, 2022 I wouldn't know how to start. Besides, somebody'd just come along and re-edit it!😃 Wikifunding is going on. Every time I've looked at it last two weeks they "appeal" to my generosity. They keep count of how many times they ask too! Link to comment Share on other sites More sharing options...

No picture just a description of the switch and how to use it. 1 Link to comment Share on other sites More sharing options...
Jim Anselmo Posted August 15, 2022 Share Posted August 15, 2022 I recently took one out of a 1960 Invicta Wagon that I parted out. Wasn't sure what is was till I did some Google searching. 1 Link to comment Share on other sites More sharing options...
Frank DuVal Posted August 17, 2022 Share Posted August 17, 2022 A high optioned 60 wagon. I hope it was a total rust bucket by upstate New York standards. Link to comment Share on other sites More sharing options...

Frank DuVal Posted August 22, 2022 Share Posted August 22, 2022 Typical, does not look rusted to us easterners...😲 I do not even see any rust in that picture, where was the rust? And those finned brake drums are valuable if not oversize. 1 Link to comment Share on other sites More sharing options...

Obviously a tree got the roof but the rest is ??? To have had the Twilight Sentinel my money says that Invicta was a pretty loaded and luxurious car for its time, and not exactly common either. 1 Link to comment Share on other sites More sharing options...
EmTee Posted August 23, 2022 Share Posted August 23, 2022 Highly optioned and in that color it must have looked gorgeous in the driveway. Link to comment Share on other sites More sharing options...
61polara Posted August 23, 2022 Share Posted August 23, 2022 In many earlier years, Cadillac would not use a new feature or option until it was proven in another line. In the 1940-1960's Oldsmobile or Buick got the option a year before Cadillac for field testing of a new accessory so there would be no problem on a Cadillac. 1 Link to comment Share on other sites More sharing options...
rocketraider Posted August 24, 2022 Author Share Posted August 24, 2022 And then along came the late 70s and early 80s...🙄 Well acquainted with Oldsmobile's reputation as GM's "gadget division". The nice gadgets have certainly made me swear over the years 🤬 but it is satisfying when you finally get the thing to work! Link to comment Share on other sites More sharing options...
