Process for changing puddle lamps '15 GT

The puddle lamps install from below the door. You'll need a pick or a small pocket flat screw driver. Under the little squared off end there is a tang that needs to be pushed toward the body of the puddle light. As you push the plastic tang under that side gently pull the assembly out. It's removed by pulling that side out first. Once out you can unplug it. ( make sure the wires don't go inside the door or you'll be fishing ) Plug the new one up and pop it in rounded side first and then snap in the end with the tang.

Easy peasy
