Weird rear light issue

[Tem]

Sometimes...and that's very rarely...like 4-5 times now, I've had a weird electrical issue on the left rear light. When I use the turn signal (to the left) AND brakes at the same time, the signal flashes quickly, as if a bulb was dead. The problem is that the bulbs are just fine and it never does that when I try to make it happen. And there aren't any loose wires on the bulbs either, which could sometimes make contact and sometimes not.

Now a friend of mine was driving behind me when that happened and he said that the rear light was also flashing with the turn signal when that happened.

I tried to browse the wiring from bgb, but can't figure out what could cause that. Other than bad ground, which tend to cause weird stuff, but the grounds seem to be good. Any ideas?  s:? :? s:?

Hi,

In my humble experience these issues are normally caused by bad earth as you have previously referenced.

I'd check all the options again!

Ive also had this and the bulb went very shortly after. Once id changed the bulb it seemed to cure the issue.
