This morning driving back home from work in the early hours I noticed a strange fault with the passenger side indicator on going round a round about. The knocking noise it makes was a lot more rapid than usual.

I investigated tonight and it turns out when turning the headlights on, it also illuminates the passenger side wing mirror indictator and I think the indicator in the headlight. The tail lights are normal n and it is only the front passenger side.

It is as if when turning the headlights on there is a trickle of power also going to the indicators so that they stay illuminated and solid. When I actually do come to use the passenger side indicator of flashes quite rapidly. The problem doesn't occur with the side lights.

Can any one offer up any advice on resolving the problem as I obviously need to fix this asap
