I drive a 1998 C70.
I am one of those guys that likes to drive with my parking lights on during the day....I'm also one of those schmucks that forgets that the parking lights don't shut off with the key. I know I'm not the only one 
...Luckily I haven't killed the battery.
It's hard to remember, especially since in my wife's Hyundai, it doesn't matter which position the light switch is in, the lights automatically shut off with the key in the off position.
Is there any way that I can rewire the switch or a relay so that the parking lights turn off with the key in the off position, like it does with the headlights on? Has anyone done this?
Thanks!
