hey guys, when i'm driving down the road without my parking lights on, this check engine light "Tail light failure" doesn't come on. but when i switch on the parking lights or the head lights, this message appears. but i've checked all the damn tail lights and brake lights and no burnt ones. so i've kinda ignored it for a while, but decided to see what you guys think. oh yeah and sometimes, when i turn on the headlights or parking lights, this message doesn't immediatly come on like most of the time lately. it'll pop up like within 20 minutes of driving.
