This will turn off your lights front and rear while engine remains on.
If it is cloudy or dark then you will need to move the headlamp switch to off too.
Don't forget to turn the DRLs back on since they save lives.
Just for the benefit of anyone in the UK/Europe, the DRLs are always on and you can't turn them off - the option isn't present. EU regulations on all new cars apparently.
