There is a very good reason why manufacturers have moved to micro-switches on the door locks. It warns the driver when the door is properly closed and the lock is secure - it just ain't for courtesy lights
It another safety device.
Yes I understand what you mean but locks are two stage and there is always road noise if even a rear door is not closed properly as with a window.The old door spring switch was a good monitor of open doors if they were fitted on the rears as well--which was not often.
Still I forget we are in the nanny state how long before the doors not closed police appear?
