Just a little diagram might help explain what happens when you have a bad rear cluster earth fault

Hello there.
I'm new here! I bought a 2005 eleganza in september and it soon started beeping- telling me of brake light/ side light failure then it started doing the xmas light thing. I've now replaced the fog bulb and cleaned the earth on the passenger side.
The lights work!
Still got the beeps and failure messages though.
Any ideas? All advice greatfully accepted as I'm new to Italian cars and the fun one can have.
I only previously bought Honda and Mazda in the mistaken belief that motoring is about your car taking you from A to B without doing something new and exciting every other journey.

Oh.
It's now stopped showing failure messages.
Wahey

All the bulbs earth through a common connection, so any one can cause issues. Get back in there and clean every bulb holder and connection.

Put all the lights on at once, tail, brake, indicator, fog and reverse. That shows whether any fight.

Thanks a lot.
Love that Allessi Panda
