They have the Daytime Running Lights DRL on and didn't turn their lights on at all. They aren't burned out, they just didn't turn them on. Sometimes it's because the driver can see their lights and assume it's headlights, when it's just DRL.

That’s just my rant since I’m driving non-highways after dark home from work and noticing it more and more.

and yes even my 2013 passat notifies us that lights are out and what specific light is out. this is a feature on MOST cars made in the past 10 years. if your car tells you someone is in your blind spot it should tell you to replace a light.

we were walking back from school drop off and 9 out of 15 cars this morning did not have lights on. not headlights not daytime running. it was completely overcast, gray, and 8am.

The other night driving to wrestling practice, in pitch black, there were at least 10 cars that didnt have any lights on.

Just leave your lights on AUTO if you cannot remember to turn your lights on and off.

Their headlights are probably turned off. If it is night and you see "headlights" on but no taillights it may be because their spouse switched the headlight switch from "auto" to "off." The headlights are actually daytime running lights, which often are less bright.

Brake lights and tail lights are . . . different lights!

They do have these.
