How to Change the Fog Light Bulbs on a Hyundai Santa Fe

Updated July 20, 2017

The fog lights in a Hyundai Santa Fe have a lighting pattern designed to cut through fog. They illuminate low and wide to reduce glare. When a bulb burns out, visibility is impaired and safety is compromised. It is recommended that you replace both bulbs at the same time, because bulbs tend to dim after years of service; replacing them as a pair ensures equal lighting.

Prepare for fog light replacement by disconnecting the negative battery terminal and placing a towel or piece of carpet in front of the vehicle. The bumper will be rested on the towel or carpet in a later step.

Remove the headlights from your Hyundai Santa Fe by removing three 10 millimetre bolts that hold them in place. Grab each headlight and pivot outward to remove it. Do not disconnect the headlight wires. Each headlight only needs to be moved aside to remove one screw underneath.

Remove the bumper by loosening the screws in the expansion clip on top of the bumper. The screw fasteners that hold the bumper are plastic, and care should be taken during removal. Unscrew each one until 1/2 inch of threads show, then grasp the screw and pull out the expansion clip.

Remove the 10 millimetre screws beneath the bumper and the three Phillips-head screws at the side of the bumper near the wheel well. Gently pull the bumper forward to dislodge it, using caution not to pull too far as wires are still attached to the bumper lights.

Disconnect the lights from the bumper. While holding the bumper, unplug the side marker and fog lights. The bumper will now be free to set on a towel or piece of carpet to prevent scratches.

Remove the bulbs by rotating each socket cover 1/8th of a turn counterclockwise. This gives access to the light bulb. Disconnect the electrical connector from the bulb, then rotate the base of each bulb 1/8th of a turn counterclockwise to remove and carefully raise each bulb out of the lamp assembly.

Put on gloves before handling the bulb. The gloves prevent oils from your hand from coming into contact with the bulb, which will shorten bulb life. Carefully insert the bulb into the fog lamp assembly, using caution not to touch the sides of the assembly, as small scratches in the quartz could shorten bulb life as well. Once the bulbs are inserted and tabs are lined up, rotate the base of the bulb 1/8th of a turn clockwise to lock the bulb into position. Then plug the electrical connector into the bulb base.

Replace the socket cover by aligning tabs, insert the cover and rotate the socket cover 1/8th of a turn clockwise. Ensure that the rubber gasket does not protrude from the cover when installed, as this would prevent a proper seal, potentially allowing water to get into the lamp assembly.

Install the bumper by lifting it into position. When the bumper is close to the vehicle, connect the sockets to the side marker and fog lights.

Insert the bumper onto the vehicle. It will stay on while the bolts are being inserted. Insert the expansion clip fastener under the headlights first. Squeeze the expansion clip tabs so they will fit back into their holes, then tighten the screws. Do this for the remaining clips on top of the bumper.

Install headlights by aligning the outside edge with the body panels. Ensure that the rubber trim on each headlight fits properly around the body panel. Pivot headlights into position and tighten three 10 millimetre bolts in each headlight assembly.

Install fasteners in the lower bumper. Align the plastic edges of the wheel well covers so they are behind the edge of the bumper. Align the holes in the wheel well covers and the lower bumper edges, then insert the screws. Install the screws on the bumper sides located near each wheel well. Then tighten the remaining 10 millimetre bolts located under the bumper.

Turn on the headlights and fog lights to ensure they're all working. Also check the side marker lights and indicators for proper operation.


Ensure bulbs are cool before attempting to remove them.
