sidelights flashing with indicators

[reeves172]

hi, i have 172 cup and the rear sidelights are dimming and brightening with the indicators on? ive checked my plug connections which are clean as new, and earth connections front and back both clean, checked bulbs no dual filement in a single ect and still cant cure it!
i looked at some previous threads all saying same things connections and earth ect
still does it the same with engine running, and fog light symbol lights up on dash when braking which i hear also points to earth/ connectors.


just wondered if anyone else has had this problem?

any advice? thanks

Have you had the UCH out and checked for water ingress?
