Just in case someone finds useful. I really like the way these LED side marker replacements look over the OEM reflector-style lights. Cheap and easy upgrade to make.

I would have liked to get these as well, but they do not have them for the '18 -'19 MY's 😕
On a side note, for some places it is illegal to go with blacked out, although I doubt any L.E.O. would notice or even bother unless the area is really gung ho on this kind of stuff.
As another aside, if the area where you live has vehicle safety inspections, and the blackout is illegal, the car won't pass.

I might go with the clear lens ones on my white diamond. It should blend in nicely.The product description has this quote:
"Connect the LED side marker lights to your turn signal light harnesses to create a turn signals feature! This will enhance your Caddy's luxurious presence by adding additional safety and visibility features."

I wonder how it would work out in actual practice? Might open a can of worms.

Well I pulled the trigger on these. I didn't necessarily love the ones on Amazon. I found these on eBay. They may be the same thing but the photos were just better and description was better on eBay. I was looking for clear. Very happy with these. Looks great when they are off.

SIMPLE to install.

I just ordered the clear ones for my White Diamond Car from EBay for $33.11. They are being shipped from CA and should arrive by 2/17. Thanks for the “heads up” on this item. It will certainly improve the looks of my car to replace the amber color on the fender with a clear lens. Can’t understand why it was built that way to begin with???? A black car with the smoke lens is real cool.

I just got mine as well. Installation was very simple once I had installed the 1st one! Things went awry when after I was able to easily remove the old lamp, I unplugged it from the housing but the new lamp did not plug right in! I thought at 1st I had ordered one for the wrong car but I looked it up & it was for the right car. After fumbling with it for a few minutes and right before I almost tried to "cut" the plastic to force it to fit, I realized that the new lamp plugged into the lamp socket, not directly into the harness! I should have paid more attention to the video!! lol The 2nd one was replaced in minutes.

I must have missed the LED reverse lights as well because the existing reverse lights are horrible!

Sadly the Zevo LED bulbs remained dimly lit when installed. I ordered 921 LED harnesses with resistors from Amazon because I really like how the Zevo bulbs look when full bright. I also ordered a set of bulbs from LasFit that are supposed to fix the issue. The person I spoke with on the phone before ordering said they had reports that it was 50/50 if they would work correctly on late model GM cars. They have a 45 day return policy so I'll try them too.

I finally got around to replacing the reverse lamps & also the license plate lamps. The license plate lamps were very easy to replace but the reverse lamps were a PITA!!!! But once they were all replaced, what a difference!! I never realized how bad the lighting was in the back of the car. The position & brightness of the reverse lamps are horrible but the new LED's definitely make a difference! I ordered all the lamps from Amazon & they were immediately delivered. The license lamps came in a package of 10 for $9.99 & the 1st one I used did not work. Since I had so many left over, I looked around to see what other lamps * could change. The only ones I could find were the glove compartment & console lamps. The glove compartment looked fairly difficult to change so I decided to leave that one alone but the console lamp looked pretty easy to change which it was and what a difference that made as well! Cadillac should exclusively use LED's!!

On a side note, when I was removing the trim plate right in front of the arm rest & right behind the gear shifter, I noticed underneath it there was a plug in a harness with nothing plugged into it. It was just sitting there, underneath that small trim piece with nothing to plug into it. I should have taken a picture of it when I had it disassembled but I didn't think about it. It looks like it would go to some sort of switch that would be on top of that trim piece but I looked through the manual & could not find any switch that would be there. Does anyone have any idea what it is for?
