31 LaSalle Posted November 19, 2023 Share Posted November 19, 2023 I recently posted a question on the Cadillac/Lasalle section where my question was which side of the headlight does the green jewel go and which side the red jewel go I originally thought they were only fitted to the Lasalle and Cadillac but have since learned Packards of that vintage fitted them as well anyway to get to the point of my post what I would like to know is what was the purpose of these jewels in the side of headlamps Thank You Link to comment Share on other sites More sharing options...
29StutzM Posted November 19, 2023 Share Posted November 19, 2023 31 LaSalle My 29 Stutz M also have these jewels. The red one goes on the drivers side and the green one goes on the Passenger side. I think it has something to do with port and starboard??? 1 1 Link to comment Share on other sites More sharing options...
JACK M Posted November 19, 2023 Share Posted November 19, 2023 Well, if you look at an airplane flying above you at night, you can see which side of the aircraft you are looking at. Port is the left side going forward and is red. Starboard us the right side going forward and is green. Works if you can see boats or ships at night too. You can tell what direction it is headed. 2 1 Link to comment Share on other sites More sharing options...
wayne sheldon Posted November 19, 2023 Share Posted November 19, 2023 It supposedly also indicates "right of way" (although those little jewels my be tough to see in the dark?). With the red jewel on the left/port side, a driver approaching from your left should see the red jewel and know to stop because you are on his right and you have the right of way. The drivers coming from your right/starboard side would have the right of way over you, and you should see their red jewel while they see your green jewel telling them to go as they have the right of way. That all did originate in maritime rules (although I never got involved in boating and actually know little about it). The 1925 Studebaker I had many years ago had the jewels in the cowl lights. 1 Link to comment Share on other sites More sharing options...

wayne sheldon Posted November 20, 2023 Share Posted November 20, 2023 As I said, I was never really into boats or boating. However, always trying to learn about almost anything, I have spoken with people that really were into those money pits (a small hole in the water one throws lots of money into I have been told!). They have told me "port" and "left" both have four letters and end in "t". I was also once told Starboard and right both have more than four letters (makes sense?), and both have an "r" in them. To which I questioned that doesn't "port" also have an "r" in it? And by the way, doesn't "right" also end with a "t"? (I think one of them got mad at me?) Regardless, the four letters and "t" works well enough that on the rare occasions I need to, I can quickly figure out what someone means. I think? The green or red I just visualize the right of way. Of course, one should never count on the other driver to yield the right of way when they are supposed to. Way too many times I have had to avoid a collision when I clearly had the legal right of way. 1 Link to comment Share on other sites More sharing options...
Gunsmoke Posted November 20, 2023 Share Posted November 20, 2023 My easy way to remember these terms is all the short words go together (red, left, port) and all the long words go together (green, right, starboard). Since no one today will understand the port/starboard message, you might consider saving the original jewels and putting a pair of orange jewels in as side marker lights and tell people LaSalle's were way ahead of their time. 1 2 Link to comment Share on other sites More sharing options...

28 Chrysler Posted November 20, 2023 Share Posted November 20, 2023 I spent most of my childhood on the Mississippi. Red is for the port side. Most Port wine is red. Starboard is on the right while facing forward. White goes on the stern. My two shepherds know port and starboard for turning on walks and hikes.

zepher Posted November 20, 2023 Share Posted November 20, 2023 The '24 Chrysler roadsters have small marker light assemblies just rearward of the door openings with red and green jeweled lenses. I would hate to try and source original jewels today. 1 Link to comment Share on other sites More sharing options...

I will have to see if I can find a picture as my uncle owns the car and he doesn't live very close. Edit: Zoom in an you can see the marker light assembly. The jewels are not in them as this was taken while the car was being put back together after paint.

HI zepher Thank you so much for the picture I would say they are the same lights I have seen a few pictures of these lights mounted in various positions on Chrysler cars which makes me wonder are these Chrysler parts or aftermarket ??? NICE CAR 1 Link to comment Share on other sites More sharing options...

No idea if they were a factory item or an aftermarket item. 1 Link to comment Share on other sites More sharing options...

Which would put their marker lights on the wrong side. 🤪 1 hour ago, Marty Roth said: Back in the 1950s Power Squadron course, we learned: Red to Right on Return These are navigational rules. Entering a bay (or port, or channel) the red marker buoys will be on the right side of the channel and green on the left side of the channel. These will guide you thru the navigable parts of the route. Red, right, return. Pretty much always upriver. I screwed this up once and found myself grounded in the middle of the Columbia River as the channel was way over near one side of the river. In my defense, it was dark. And fortunately, only sand. 3 Link to comment Share on other sites More sharing options...
