This guide will show you how to install the 2015-up 6th generation Ford Mustang LED rear side marker lights. Ideal for upgrading your stock side markers, your tail end will be able to achieve a brighter, more vibrant look. This can easily be done with plug-and-play action.
Step 1: Release the Stock Side Marker Lights From Your Ford Mustang.
Reach from behind to undo the clip. We recommend using a towel to shield your hand and wrist from the hot exhaust or waiting for the exhaust to cool down so you don't burn yourself.
Step 2: Remove the OEM Side Marker Light From Its Stock Harness.
Pull out the side marker housing and twist/unlock the incandescent bulb from the base of the harness.
Step 3: Plug in the Rear LED Side Marker Light.
Make sure you tuck in the wires so water doesn't get into the wires and connector.
Repeat steps 1-3 for the other side.
