Optix Autolabs - Compatible with 2015-2017 Ford Mustang Smoked LED Rear Side Marker Light - LED Side Lamp Replacement Housing

First off, let me say that these will most likely fit 18 and 19 models as the side-markers are the same as 15-17 models. CJPonyParts and American Muscle have their vividline and diode dynamics mustang side-markers and they state that they fit all 15-19 models, so that's something worth noting since these are very similar if not identical. Although I haven't had them for very long in my opinion (just over a year) on my 2017 Mustang GT CS, it has seen just over 13,000 miles as its my daily driver, it has seen rain, snow and just about everything in between (it even survived Hurricane Harvey which hit Houston pretty significantly and so that should go to say that these Optix side-markers are very durable and shouldn't give you any problems. Install was very easy (if a 19 year old kid can do it in 5 minutes, maybe 10 minutes at MOST, I'm positive that it'll be easy for you to install also). As to looks... They look fantastic compared to the stock ones that tend to be an eyesore, It's nice and subtle and the price is definitely a plus since they're basically half the price of the big 3 mustang aftermarket websites. The smoked tint is definitely nice too, I was on edge between the smoked and regular red tinted housing and I can proudly say that I'm glad I went with the smoked tail lights and I will eventually bring it all together by tinting the brake lights and everything else.All in all, I would say that these are a solid buy if you're looking for a nice subtle detail that'll bring your mustang into the 21st century and for a good price compared to the other side markers that are practically the same. I would encourage picking these up if this is what you're looking for!

I received this item quickly and it was packaged well. Installation was a breeze with YouTube but the item did not come with instructions. This item is about half the price of a competitor and it looks amazing, works great, and really improves the look of the S550 Mustang.

Quality product for half the price of other competitors. Worked great on my 2015 Mustang GT, plug and play

It was a good product while it worked. Driver side slowly died out it lasted just over a month. Still waiting for a reply from the company about the warranty so just going to return them.

Fit just like stock. They look good I'll update if they stop working or get condensation inside the lens. 19 mustang gt

These side marker lights are awesome!! Easy to install and they look great. Way better then the stock lights. As soon as my friend saw them he got a set for his car to.

Very easy to install, they look great
