      Lighting Appearance Upgrade. When lit the OEM rear side markers have an unsightly hot spot that looks dreadful. Installing a set of Smoked Side Markers will replace that ugly hot spot with a bright red, razor sharp LED strip for bold custom styling. A set of Smoked LED Side Marker Lights are a great way to upgrade the exterior appearance of your 2015-2020 S550 Mustang.

      SMD Technology. 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 smoked optical reflector looks identical to the original factory part and is ultrasonically welded together to prevent moisture from entering the housing.

      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 Vividline Smoked 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.

        Look great but quality is questionable

        Purchased a set and, upon installation, discovered the negative wire was not soldered to the board inside the marker. This meant I had to return the set for another pair, something I did not think would happen with expensive Raxiom lighting. Install can be tricky and there's not much give in the wiring harness to slip the marker out for bulb replacement. All in all, it looks good but I do wonder how long they will last. Also, these are double and triple the cost of comparable smoked markers.

        They are super easy to install, won’t take over 20 min. Looks amazing in daylight and when there are on during the night. Premium looks compare to the stock ones

        Great smoked look

        These looks great on my Black GT, the smoked look fits in with the body color and the LED strip lights throughout the side marker and looks sharp. Was very easy to install, took me 5 minutes as I had the bumper off doing another install, it may be a little tougher with the bumper on but it's not necessary to take it off.

        Look absolutely amazing !!!!!

        These look amazing and take literally 4 minutes to install. The only downfall is the cost, as I feel $80 is kinda steep for 2 little marker-lights.

        Excellent product

        This product is just what was missing with the black accent package when I order my ingot gray mustang. It totally give the sinner look I needed, and at night the led red laser colour is so beautiful.

        Great at first

        I initially purchase 7/2017 and got about 6 months before one side started to flicker and turn off completely. AmericanMuscle was great and did a return. I received the new set 2/2018 this set made 11 months before I started having issues. This time the left side is barely lit, to the point of being unable to see in the sun. The right side is half dim and half "full" brightness. I really like the side markers when they are new and bright...
