Hey guys. So I got pulled over while driving at night due to my tailights not working. I have a 2010 chevy hhr and everything else is fine (brake lights, signals). I replaced bulbs and it's still the same. Please help!!!

 

Did you check the fuse and relay for the parking lamps ?

 

Welcome to the site, X2 what FMG asked

 

Might be something wrong with the light sensor on the dash. This would cause you to be operating with only the daytime running lights(DRL).

 

That would be the next step, that and ground wires or burnt bulb sockets.
here are the items to check

True on the other possibilities but let's start with most likely and easiest to check for the noob.

 

Turning the headlights to "on" instead of having them set to "auto" would see if they actually do work...

 

They all have the same 2 ground points.

 

Thanks guys for the feedback and especially @firemangeorge , heeded your advice and it works now.

 

Awesome, glad you got it fixed, enjoy the ride.
