850: indicator problems

[stephen clare]

Hi
First time on here and posting for my old Dad, who is 86, and loves his Volvo 850 estate, which goes on and on and has been a fantastic car over his very long ownership. The indicators have been playing up. Fast ticking of the audible sound, like a bulb gone. I helped him out today by identifying that the offside front was the one not working. Both front lenses obviously had water sitting in, so cleaned them out and replaced all 4 bulbs on the front- the 2 daylight bulbs, and the indicators, which we put LEDs in to make em nice and bright.
They're all working now, but the 2 fronts are flashing quickly, and when the ignition is, the audible ticking signal is ticking away, even when he isn't signalling with the indicators.
Any advice welcome
