2022-2025 Ioniq 5 Headlight Guide: Decoding Projector vs. Reflector and Trim Level Differences
This definitive guide explains the critical differences between Ioniq 5 headlight types, identifies known issues, and details what to check when buying a used assembly.
- Headlight types (Reflector vs. Projector) are tied to trim levels and are NOT interchangeable without major wiring modifications.
- Crucially, the 2023+ US-market SEL trim was downgraded to the inferior Reflector headlights, unlike the 2022 SEL which had Projector lights.
- Temporary condensation is considered normal by Hyundai (TSB 23-BD-002H), but pooled water means the unit has failed.
- A new OEM assembly is extremely expensive (over $1700), making a verified, used OEM part the best value for replacement.
Headlight Versions: The Critical Difference Between Trims
The single most important factor when purchasing a 2022-2025 Hyundai Ioniq 5 headlight is understanding the difference between trim levels, as they are not interchangeable. Using the wrong type can lead to connection issues, error codes, and improper function.
Compatibility Trap: For the 2023 model year in the US market, Hyundai downgraded the SEL trim's headlights from the superior Projector type to the base Reflector type. A 2022 SEL uses a different, better headlight than a 2023 SEL. Always verify the part number and headlight type for the specific vehicle you are working on.
| Trim Level | Headlight Type | Key Features |
|---|---|---|
| SE / SE Standard Range | MFR (Multi-Faceted Reflector) LED | This is the base-level headlight. It uses LEDs that shine into a chrome reflector bowl to create the beam. Performance is considered adequate but noticeably inferior to the projector version. |
| SEL (2022) / Limited | Projector LED | This is the premium headlight. It uses a lens to focus the light from the LED, creating a sharper, brighter, and more controlled beam pattern for better visibility. |
| SEL (2023-2025) | MFR (Multi-Faceted Reflector) LED | For these model years, the SEL trim was equipped with the same base-level Reflector headlights as the SE trim, a significant downgrade from the 2022 SEL. |
The Limited trim also features premium front LED accent lighting (sometimes called the 'mustache' light bar) that is not present on the SE or later-year SEL trims.
Known Issues, Recalls, and TSBs
Recall 25V-373: Incorrect Headlight Aiming Label
Hyundai issued a recall for approximately 10,409 model year 2025 Ioniq 5 vehicles due to an incorrect aiming label on the right-side headlight assembly. The headlights were aimed correctly at the factory. However, the incorrect label could cause a technician to misalign the headlight during future service, potentially reducing visibility. The remedy involves Hyundai mailing the correct label to owners with instructions for application. This is not a defect in the headlight's function but is important to be aware of if servicing a 2025 model.
TSB 23-BD-002H: Headlight Condensation
A very common concern among owners is the appearance of moisture or fog inside the headlight lens, especially after a car wash or in cold, damp weather. Hyundai has released a Technical Service Bulletin (TSB) addressing this, stating that a small amount of temporary condensation is a normal occurrence due to atmospheric changes and the vented design of modern headlights. This fog should clear on its own after driving with the lights on. However, if you see water pooling at the bottom of the housing or large water droplets and streaks that do not go away, the assembly's seal has failed and it needs to be replaced.
Symptoms of a Failing Ioniq 5 Headlight
- Dim or Flickering Light: An LED segment that flickers, appears dim, or changes color (e.g., turns purple or yellow) often indicates a failing internal LED driver or the LED element itself.
- Complete Failure: One or more functions of the headlight (low beam, high beam, DRL) stop working entirely. This could be the assembly or a related electrical issue.
- Warning Lights: A headlight malfunction may trigger a warning message on the dashboard.
- Persistent Moisture: As noted above, condensation that never clears or results in standing water inside the lens is a sign of a failed seal.
- Electrical System Issues: While not a direct headlight failure, be aware that the Ioniq 5 has documented issues with its Integrated Charging Control Unit (ICCU) and 12V battery system. These problems can cause a wide range of electrical gremlins, which could potentially manifest as lighting problems.
Buying a Used Headlight Assembly: A Buyer's Guide
Given that a new OEM headlight assembly can cost over $1,700 from a dealer, a quality used OEM part is an excellent value. Here’s what to inspect:
- Verify the Part Number and Type: This is the most crucial step. Match the OEM part number exactly. Visually confirm you are buying the correct type (Reflector vs. Projector) for your vehicle's trim and model year. Remember the 2022 vs. 2023 SEL trap!
- Inspect the Lens: Look for deep scratches, rock chips, and 'crazing' (a network of fine cracks from UV damage). Minor scuffs can often be polished out, but deep cracks cannot. Check for any signs of yellowing or hazing.
- Check for Moisture Damage: Look for a 'water line' or mineral deposits on the inside of the lens or on the chrome/black plastic interior. This indicates the unit had a failed seal and should be avoided.
- Examine All Mounting Tabs: The assembly is held in by several plastic tabs. These are brittle and often break during removal. Ensure all tabs are intact. A single broken tab can cause the headlight to vibrate or sit improperly, affecting alignment.
- Inspect the Housing: Check the black plastic rear housing for any cracks or damage, especially around the mounting points.
- Check the Connector: Ensure the main electrical connector and its pins are clean, dry, and free of corrosion. The initial data for this part specifies an 11-pin plug; make sure it matches your vehicle's harness.
Pro Tip: For a critical electronic component like this, a used OEM part is almost always a better choice than a cheap new aftermarket one. OEM units are built to Hyundai's exact standards for light output, beam pattern, and durability. Aftermarket units can have poor fitment, inferior lighting, and may not communicate correctly with the vehicle's electronics.
Replacement and Calibration
Replacing the headlight assembly on an Ioniq 5 is a moderately difficult job that typically requires removing the front bumper cover to access all the bolts. 🎬 Watch: Step-by-step guide to removing the front bumper cover. While it can be done by an experienced DIY mechanic, it is more involved than on older vehicles.
Aiming and Alignment
After installation, the headlight must be properly aimed. An improperly aimed headlight can blind oncoming drivers or fail to illuminate the road adequately. While the owner's manual provides a basic procedure, professional alignment using specialized equipment is recommended for accuracy. 🎬 See what correctly adjusted headlights look like on the road. Some owners have reported that high beams are aimed too low from the factory, 🎬 Watch: How to properly adjust your high beam alignment. so it's worth checking and adjusting after any service.
Warning: Attempting to upgrade from a base Reflector (SE) headlight to a premium Projector (Limited) headlight is not a simple plug-and-play swap. The wiring harnesses and connectors are different and would require significant modification.

Frequently Asked Questions (FAQ)
Can I upgrade my SE headlights to the Limited's projector style?
No, not easily. The wiring harnesses and electrical connectors for the Reflector and Projector headlights are different. It would require extensive and costly custom wiring to make them work.
My headlight is foggy inside. Is it broken?
Not necessarily. Hyundai states that some temporary condensation after a car wash or in humid weather is normal and will clear on its own. However, if you see large water droplets, streaks, or water pooling at the bottom of the light, the seal has failed and the assembly needs to be replaced.
Does a replacement headlight need to be programmed by the dealer?
No, the headlight assembly itself does not typically require programming. However, if your vehicle is equipped with advanced driver-assistance systems (ADAS) that use cameras or sensors near the headlight, those systems may require recalibration after the bumper has been removed and reinstalled.
What's the real difference between Reflector and Projector LEDs?
A Reflector headlight uses a chrome bowl to bounce light forward, which can create a less focused beam with more glare. A Projector headlight uses a lens to focus the light into a sharp, well-defined beam with a distinct cutoff, providing better illumination of the road without blinding other drivers. For the Ioniq 5, the difference in nighttime visibility is significant.
