On my Mazda 6 saloon, there are two pairs of lights on the inside of the roof, one pair at the front, and one pair centrally placed. Both pairs light up when the car is unlocked, and the front pair turns off a few seconds after I have got in the car and shut the door. The central pair however stay illuminated until I have got out and locked the car. I haven't noticed this before, and I have had the car over a year. I noticed it yesterday because for the first time in months I have had to drive at night, and the inside of the car was quite well lit up as I drove. Is there a switch somewhere that I may have accidently moved (I seem to occasionally catch the switch that controls whether the door mirrors fold in/out automatically or not)? The handbook (as usual) is useless in finding solutions to occasional problems - the door mirror thing took me ages to track down why the mirrors stayed folded.
Thanks for any help
