I would like to activate the coming home/leaving home lights on my car. I have no auto light switch. I think, having read many posts on here, that i can alter the computer settings to enable this function (i do know that this will mean the lights will be on during the day as well). Can anyone advise me where in the computer, i can find the settings that need to be altered and more importantly what i need to type to make the car do this? Many thanks
