I have a 2015 Leon fr and when I turn the ignition off all lights go off apart from one at the back left which I think is a break light. Its led so I can't just change the bulb. I've taken the light housing out and cleaned it it doing the same. I've taken the light switch out and had a look at connections they seem fine. I have ordered another switch and will see if that does anything when it comes. Could it be a fuse?
