    Lighting Appearance Upgrade. Upgrade the exterior appearance of your 2015-2019 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 Vividline Red LED Rear Quarter Panel Side Marker Lights are designed to fit all 2015-2019 Mustangs including the V6, EcoBoost, GT and Shelby GT350 models. Includes driver and passenger side markers.

      Slick and Modern!

      I bought those side markers because of the look and after 15 minutes of installation by myself I got the same look I saw online... Love this little light upgrade!!! After a whole month they are working perfectly! Fully recommend this product.

      Nice touch

      These look great. The install was super easy. I picked up my new 2018 GT, drove it home and put them in on my driveway in about 5 minutes.

      Overall good addition

      Easy to install, even from the ground. Would have been easier if I had done it on a lift. Even so, took less than an hour. They look much better than OEM incandescent markers. Not a striking change, but an improvement nonetheless.

      Left side went dim

      The left side went dim on the second day. Had bodey work done so it could be related to bodey shop removing the side markers improperly, the wiring and connectors seem to decompose, from MA

      led rear side marker lights.

      These look so much better than the standard reflector.

      Subtle detail

      The stock bulb was so bad that I honestly thought it was just a reflector. The added LED definitely gives the sidemarker a more calibrated appearance with the iconic brake lights; it looks especially sweet at night. The only issue is that the new Kit doesn't "click" when plugged into the socket; it almost feels like it's just sitting in the housing unit. To ensure that it isn't loose/doesn't short in the future, especially after some spirited dirving, I strongly recommend placing a thin strip of electric tape/harness tape to ensure the LED kit and housing unit are joined more firmly. Other than that, I am very happy with this item.

      Junk. Don't buy these.

      They look beautiful and work great for a few months, but because the electrical connection is just hanging loose instead of mounted to the unit, the internal wires eventually break from vibration. Both of mine fried in less than nine months/10,000 miles.
