Every time I switch the headlights off, it can take from 5 secs to 5 mins for the headlights to go out. The rear lights go out straight away but the headlights remain on. Does anyone know what could be causing this? I have a reciept for a light regulator that was replaced in april just before I bought it, but as I have never heard of it I don't know if that could be related or not?
Help! its doing my fooking head in waiting ages for them to go out!

Those cars have something called a LKM and that plays up now and again. If you can get your self down to a scrap yeard you will find the module near the Main Engine ECU its thin and black next to a bunch of large silver boxes with large connectors. (You need a very large philips screw driver to access the pannel or you will round the bolts off)

I had a rough idea it might be that. is that also known as a light regulator?
