One of the reasons I have a defender is that I HATE cars that are smarter than their drivers; headlights that turn on automatically in the dark, automatic parking brakes, <BONG> your keys are in the ignition, <BONG> the door is open, <BONG> you shouldn't be allowed to drive etc. etc. However, for my arrogance, the gods have seen fit to have me leave the parking lights on a few times, and it might only be a matter of time before I come back to a dimly glowing truck with a flat battery.
So, I think I should wire up a lights-on warning 'buzzer'. Wiring it isn't a problem, but I don't want a buzzer. I'd like a single "by-the-way dude, the lights are on" beep rather than the usual "YOU F*&"£$£$G MORON, YOU ARE GOING TO DIE, DIE, DIE, DIE, DIE" claxon type affair usually found.
So, where would I find such a buzzer/sounder before my battery goes fla..... ?
