How do i install a stock replacement fog light on a 2007 hyundai sonata?

Light or fog light lamps? On what vehicle? Please re-post.

Or are you trying to change them from On to Off, or vice versa? Please re-post.

You have to go to the dealership and have them reset it. My wife's has been on for 4 years on her sonata, doesn't hurt anything.

You have to turn the right or left wheel inside "whichever fog lamp needs replacing" and the light housing should be exposed on front of wheel housing.

On the bottom side of the car under the fog light area there will be an inspection cover. it is held in place by two plastic trim clips. they will have what looks like a philips head on the screw. remove both of these then pull out the retainer (they are set up like a dry wall anchor). pull back the cover and unplug the bulb. twist the bulb counter clock wise to remove. install in reverse order.
Good luck!! EJ

You have to remove or loosen the inner fender well on that side, and there are three 10mm bolts holding it to the bumper cover.

Look under the bumper and you will see two large phillips head screws right in front of the wheels. Take these two screws out and bend/move the plastice piece out of the way. Now you can easily get to the bulb. There is a cap that twists off that protects the wires and back of the bulb. Twist this off and then remove the plug portion from the back of the bulb. The bulb then turns 1/4 to 1/2 revolution to loosen and remove. Reverse steps for installation.

you will probably have to replace the bulb
