Left fog light stopped working..

Most likely a bad bulb. Both fogs typically have the same fuse so if the right is still working I would chk the bulb

 

you can go to auto zone our a ]nother parts store they will help you get it out but what i usually do if one light goes out I change both because i think if one goes the next will go soon just me it's a bulb problem might be made in China Ha! Ha.

 

You would have to loosen the plastic corner piece under the bumper to gain access to the fof light. Not sure if it can be gotten to on the Prii C from under the hood......I know it cant be done on the liftback.

 

On the left, a kid with a skinny arm can reach down and twist it out. Not so on right. Id probably let the dealer do it under warranty.

And still change them both!

 

Not sure what your question means. The right one will have to be removed after you drop the underpinning on that side or loosen the inner fender so you can get to it. I found that the left one can be taken out from the top if your arm is skinny enough. Mine is too fat to get down past everything. You can shine a flashlight down there and see it from the top.
I just installed the fog lights a couple of weekends ago.
