Yes, fog lights can be installed in the 2004 Chevy Impala. These lights come standard in this make and model.
Are both lights coming on and staying on? sometimes when a light is out on the front or rear the lights just come on and will not blink.
The most probable answer is that you have a bad flasher.
Does the turn signal also blink? If so, you have two wires touching. What happens when you put the vehicle in reverse and the backup light is supposed to come on? If the turn signal lights up and the backup light doesn't, you have the bulbs in the wrong socket.
What year is your Impala? 2001
