I agree on just putting the headlights on. Those DRL's are stupid. During rainy, foggy weather, people think they are good with just the DRL's on, but the taillights need to be on in foggy weather too.
Also, on newish GM vehicles, especially SUV's and trucks, there is almost always one light burned out! They must put some cheap damn bulbs in there.
