2019-2020 Hyundai Santa Fe Fog Light: Halogen vs. LED Part Number Guide

Halogen vs. LED: A Critical Distinction

The most important factor when replacing a fog light on a 2019-2020 Hyundai Santa Fe is identifying whether your vehicle is equipped with halogen or LED units. These two types are not interchangeable without modification due to different electrical connectors, wiring, and significantly different costs. Installing the wrong type will result in a part that does not fit or function. The original vetted data incorrectly listed 92202S1100 as a halogen part; it is, in fact, the LED version.

You can typically identify which version you have by looking at the light output; halogen lights have a warmer, yellowish hue, while LEDs produce a bright, white light. The LED versions were generally equipped on higher trim levels like the Limited and Ultimate, while mid-to-lower trims like the SE and SEL came with halogen lights.

Part Number and Price Comparison

Use this table to verify the correct part number for your needs. Note the significant price difference between the OEM halogen and LED assemblies.

Symptoms of a Failing Fog Light Assembly

• Fog Light is Out: The most obvious symptom is a non-functional fog light. This is often just a burnt-out H8 halogen bulb, which can be replaced separately. If the assembly is an LED unit, the entire assembly must be replaced as the LEDs are not serviceable.
• Cracked or Damaged Lens: The lens can be cracked by road debris like rocks. This not only looks bad but allows moisture to enter the housing, which can short out the bulb and corrode electrical connections.
• Moisture or Condensation Inside: Finding a light fog or small water droplets inside the lens is a common issue. While Hyundai states that minor condensation that clears on its own is normal due to vented housings, excessive water that pools or leaves streaks indicates a failed seal or a crack in the housing.
• Dim or Flickering Light: A flickering light can point to a failing bulb, a loose connection at the bulb's socket, or a problem with the vehicle's wiring.

Known Issues, TSBs, and Recalls

As of mid-2024, there are no specific recalls or Technical Service Bulletins (TSBs) from Hyundai or the NHTSA directly addressing the fog light assemblies on the 2019-2020 Santa Fe. The primary recalls for these model years concern a potential fire risk from an accessory tow hitch wiring harness and improperly bonded windshields.

The most frequently reported owner complaint is moisture and condensation inside the light housings. Hyundai has a general bulletin (23-BD-002H) that describes how to differentiate between normal condensation, which is a natural occurrence in vented lamp assemblies, and a water leak that requires repair. According to the bulletin, if water is pooling at the bottom of the lamp or does not clear after running the lights for several minutes, it may be considered a warrantable defect caused by a bad seal or crack.

Buying a Used Fog Light Assembly

Purchasing a used OEM fog light assembly can be a cost-effective alternative to a new part, especially considering the high price of the LED units. However, careful inspection is crucial.

• Verify the Part Number: First and foremost, confirm you are buying the correct version (Halogen or LED) for your vehicle. Double-check the part number on the housing if possible.
• Inspect All Mounting Tabs: The plastic mounting tabs are brittle and often break during minor impacts or even improper removal. Ensure all tabs are present and free of cracks. A broken tab will result in a loose fit and improper alignment.
• Check the Lens Condition: Look for deep scratches, rock chips, and cracks. Pay close attention to the edges where the lens meets the black plastic housing, as this is a common point for seals to fail.
• Look for Signs of Moisture: Check the inside of the lens for dried water spots, mineral deposits, or a hazy film. These are all signs that the assembly has had a water leak in the past and is likely to fog up again.
• Examine the Bulb Socket/Connector: For halogen units, check the area where the bulb twists in for any signs of heat damage or corrosion. For both types, ensure the electrical connector on the back is clean and undamaged.

Replacement and Installation Guide

Replacing the fog light assembly on a 2019-2020 Santa Fe is a manageable DIY task for those with basic hand tools.

1. Access the Assembly: You do not need to remove the entire front bumper. Access is gained from underneath by removing the plastic splash shield below the fog light. 🎬 Watch this step-by-step fog light replacement video. This shield is held in by several 10mm bolts and plastic push-clips.
2. Remove the Old Assembly: Once the splash shield is moved aside, you will see the back of the fog light assembly. Disconnect the electrical connector by pressing the release tab. Then, remove the screws (typically Phillips or 10mm) holding the assembly to the bumper.
3. Install the New Assembly: Position the new assembly and secure it with the mounting screws. Reconnect the electrical connector.
4. Test the Light: Before reattaching the splash shield, turn on the fog lights to ensure the new assembly and bulb are working correctly.
5. Aim the Fog Light: Proper aiming is critical. Park the vehicle on a level surface about 25 feet from a wall. Measure the height from the ground to the center of the fog light. On the wall, make a mark at that same height. The top of the fog light beam's cutoff line should be adjusted to be about four inches below your mark on the wall. The adjuster is a small screw on the back of the assembly, which can be turned with a Phillips screwdriver to move the beam up or down.

6. Reassemble: Re-install the splash shield with all bolts and clips.
