Hello Diesel Fans,
Can someone explain this to me. What is the standing light setting for? Its on the headlight switch that only works with the key off. Its like the parking light setting,but you can set it for the right side or left side lights. This has bugged me ever since I got my car. Why would you need to turn on the parking lights for either the right side or left side for?
