Not sure if I have the solution, so thought I would check with you guys/girls.

Upon exiting my car with headlights on dipped, keys removed, I don't get any audible warning to let me know that I've left my lights on, (dipped only, as works with sidelights and also if i leave the rear fog lights on).

I have noticed that when either the sidelights or rear fogs are left on and the keys removed the instrument panel is illuminated and audible warning can be heard, but with dipped lights on the instrument panel doesn't illuminate and the audible warning doesn't activate, is this down to the bulb not working, thus in turn breaking the circuit.

I was wondering, is it just a case of replacing the faulty bulb in the instrument cluster, if so how do I do this, is there a guide anywhere?
