      Lighting Appearance Upgrade. Upgrade the exterior appearance of your 2015-2020 S550 Mustang with a set of Red LED Side Markers. When lit the factory rear side markers have an ugly hot spot that just looks horrible. Installing a set of Red Side Markers will replace that unsightly hot spot with a bright, razor sharp LED strip for impressive custom styling.

      SMD Technology. Red LED Side Markers are made in the USA and use powerful SMD LED focal strips to produce a bright laser-like light. The LEDs feature embedded transient voltage suppression and a constant-current driver to provide excellent, long lasting reliability. The red optical reflector looks identical to the original factory part and is ultrasonically welded together to prevent moisture from entering the housing.

      DOT/SAE Compliant. Red LED Side Markers not only improve the appearance of your Mustang, but they also meet or exceed the strict guidelines set forth by the U.S. Department of transportation (DOT) and the Society of Automotive Engineers (SAE) making them DOT and SAE compliant.

      Plug-and-Play Installation. Installation of these LED Side Markers is 100% plug-and-play. There is no cutting, splicing or resistors required. Just pop out your factory side markers and disconnect the wiring harness. Plug the harness into the back of the LED Side Markers and snap them in place of the old ones. It's that easy!

      Application. These Axial Red LED Rear Quarter Panel Side Marker Lights are designed to fit all 2015-2020 Mustangs including the V6, EcoBoost, GT and Shelby models. Includes driver and passenger side markers.

        Side marker

        Super looking product and even easier to install. Took less than 15 minutes a side.

        Love the look of these

        I don't know why Ford went with the single bulb on these side markers. The Vividline looks stock when they are off. I would have preferred smoked lenses but we have strict safety check laws and smoked or clear lenses will not pass. These are very bright and give the rear quarter an upscale look. It was hard getting the first stock light out but, after I figured it out, the second one came out much easier. Not sure what the difference is between the different brands, but I am very happy with these.

        Should be factory

        Nice and simple mod that honestly should be factory. Helps tie in your marker lights with all your other LEDs. Even when they're off they just look much cleaner than the factory markers.

        4 2015 GT - LexS550 Installation Time: Less than 1 Hour

        Perfect Fit

        Fills the entire length of the lens with bright LED lights. Clipped right into the stock location in about 20 min. Did it in the driveway backing up a set of ramps for easier access. Would give it 5 stars however the solder for the wires looks a little weak. May break over time but will fix it if needed.

        1 2017 V6 - jowii07 Installation Time: Less than 1 Hour

        It only lasted about 7 months.

        I don't recommend this product. When I bought it, it was working fine and looked great. However, about 7 months later, the driver side rear marker started to flicker until it stopped working. Upon closer inspection, I noticed water inside the piece, which probably corroded the electrical components and caused it to stop working. I emailed AM Customer Service to report the issue, but was told that this product only carries a 30 day warranty, which means they are currently unable to replace the part. It's unfortunate that a product this expensive has such poor craftsmanship that allows water to get inside after a period of time and damage it. It is also unfortunate that a product this expensive has such poor warranty. Now I'm out of $90 bucks, but at least I learned my lesson and I'll never buy from Vividline again!

        Easy install. Looks great.

        This was an easy install and took all of ten minutes. It took longer to carefully use very long needle nose pliers to fetch the connector out of the housing on one of the new assemblies. For some reason it was shoved way down in the hole and was hard to retrieve. Frustrating. Anyway the lights look bright and since they meet DOT /SAE standards which should make state safety inspection smooth.
