My wife just bought a 2013 UK MX5 and she seems to think that when she first got it there was a buzzer reminder for the headlights. I have checked and there is no buzzer now. Was she imagining that it had one as standard?
I do not know about the 2013 model but my 2014 has no light reminder buzzer, it has a reminder buzzer for the electric hard top though if you try to drop the top in gear or the boot is open.
How odd my 2014 has a sidelight/headlight warning buzzer
In my 2010 car it sounds when you open the driver’s door with side or headlights on and ignition key turned to off.
