Diode Dynamics LED Sidemarkers for the 2015-2023 Ford Mustang are a direct replacement for the factory units with a full LED array and OEM-grade retroreflector optics — brighter output and a much cleaner look. Available in red, smoked, or clear lens options. Here's how to install them.

Installation Instructions
Step 1 — Remove Factory Sidemarker
Reach behind the factory sidemarker and depress the tab on the side closest to the wheel well. Once unclipped, slide the sidemarker toward the wheel well to pull the housing out.
Step 2 — Disconnect and Swap
Depress the clip on the factory sidemarker housing to remove the sidemarker and bulb socket completely. Set the factory unit aside — it won't be reused. Plug the new Diode Dynamics LED sidemarker into the factory wiring harness.
Step 3 — Install New Sidemarker
Slide and clip the new LED sidemarker into place. Repeat for the other side. The install is complete.
