So I've had this intermittent issue on my right indicator only, left is fine. Basically, it works sometimes as normal, then other times it flashes fast and the front indicator doesn't flash (rear does). Obviously it's not the bulb because it does work other times.
Sometime's if I leave it on it will flash fast for a bit, then normal, then fast.
It sounds like a loose connection, but I have had the indicator out the front before to have a look and couldn't see anything obvious - gonna be fun diagnosing/finding the issue.
