Near side indicator light stays on dash when you start the car and stays dimly lit when driving along. When you stop the car and take the keys out the light goes out. When the boot or tailgate is opened the light comes back on without the keys. When you shut the boot the light goes out. Ant ideas?

Sounds like an increasingly common problem...
