Press Barkes - drivers side parking light flashes

As the title suggests.  Just noticed it today.  Brakes lights still work fine but drivers side headlight flashes too (parking lights).

Strange one I know  8O

My mk1 is haunted I think  

Faulty brake light bulb  8O

Change them …..


Cheers……….

Fixed now.  Didn't relise the bulbs have twin elements.
