Modern Vespa

Hi all, me again. I've just replaced the rear light unit which doesn't have an earth connection, the old one did. It just has the two wires..to the bulb, so I'm presuming it's earthing through the frame. The issue I'm having is I now have no rear light. I have a brake light, but only on some switch positions on the handlebar!. I also do not have a brake light triggered from the front brake lever. The head light ( dip/full) seem to work fine. Could it be an earth, I'm not even sure they worked before I changed it as I've only had the scoot a few weeks. Thanks in advance.

How many wires coming out the back of the scoot?


What colors are they?

There are like 5 or 6 different wiring setups for P125s so give us some more model details and some pics. That will help us help you.
