09 Jimny Light Warning Buzzer

Hi all, Im still fairly new to looking after jimny's, im more used to Landrovers and such.
My other half has made a habit of leaving her lights on and i lose count of how many times ive had to take her to work and recharge the battery.
Are these fitted with a headlight warning buzzer of any kind as standard? 
Just trying to work out if im repairing something existing or needing to fit a new system alltogether.
Also if anybody has a relevant Circuit Diagram thst they wouldnt mind sharing, that would make my day a lot easier, 
Many Thanks,
Tony

They have an incredibly annoying continuous buzzer for lights and key left in the ignition.

I suspect someone's removed it for that reason. probably just pulled one of the connectors, it's under the cover where the ignition keys are. 

Everything goes through the drivers door interior light switch which corrodes or at least gets worn, but does the interior light come on as it should? If so then mayb it's disconnected as above ....if the light dosen't come on , then change for passengers to check.
