2022-2026 Subaru WRX Headlight: Decoding SRH vs. Non-SRH Assemblies
This guide explains the critical differences between the standard and Steering Responsive Headlights (SRH) on the 2022-2026 Subaru WRX, which are not interchangeable.
- There are two non-interchangeable headlight types: Static LED (Base/Premium) and Steering Responsive LED (Limited/GT).
- Upgrading from the static to the SRH headlight is not possible due to different wiring and computer controls.
- Replacement of the assembly requires removing the front bumper cover.
- After installation, headlights must be manually aimed. SRH models may also require electronic calibration.
Variant Differences: Critical for Compatibility
The single most important factor when purchasing a headlight assembly for a 2022-2026 Subaru WRX is understanding the difference between trim levels. The type of headlight is directly tied to the vehicle's trim package, and they are not interchangeable due to major differences in wiring and electronic control systems.
🎬 Watch: A side-by-side comparison of Base vs. Limited headlights.Warning: You cannot upgrade a Base or Premium model to the Limited/GT headlights by simply swapping the assemblies. The wiring harnesses and computer systems are completely different. The SRH headlights rely on data signals from the car which the Base/Premium models are not equipped to send.
| Trim Level | Headlight Type | Key Features |
|---|---|---|
| Base, Premium | Static LED Headlights | Standard LED projectors for low and high beams. These do not turn with the steering wheel. The side marker/turn signal uses an incandescent bulb. |
| Limited, GT | Steering Responsive Headlights (SRH) | LED projectors that pivot left and right with steering input for improved visibility in corners. These assemblies also feature a full LED C-shaped daytime running light (DRL) and turn signal. |
Symptoms of a Failing Headlight Assembly
- Moisture or Condensation Inside Lens: This is a common issue. While Subaru notes that minor, temporary fogging can be normal with temperature changes, any significant water accumulation, large droplets, or permanent water stains indicate a failed seal. This can damage internal electronics and reduce light output.
- Dim or Non-Functioning Lights: Since these are sealed LED units, a section of the light (like the low beam or DRL) going out means the entire assembly must be replaced. Individual LED chips are not serviceable.
- "SRH Disabled" Warning Light (Limited/GT): A warning message on the dashboard indicates a fault in the adaptive headlight system. This could be caused by a failed motor in the headlight, a bad height sensor on the vehicle's suspension, or a loss of calibration.
- Cracked or Damaged Lens/Housing: Physical damage from impacts can break the lens, housing, or mounting tabs, compromising the seal and structural integrity.
Known Issues, Recalls, and Service Bulletins
As of early 2026, there are no major recalls specifically for headlight failure on the 2022-2026 WRX. However, one recall was issued that is related to the headlights:
- Recall WRA-23 (NHTSA ID 23V016): Issued for approximately 4,615 model year 2022 WRX vehicles, this recall addresses incorrect instructions in the owner's manual for adjusting the High Beam Assist function. This does not involve replacing the headlight itself; Subaru mailed owners a corrected manual insert.
Condensation is the most widely discussed issue among owners, though it is not subject to a specific recall. Subaru has a general TSB for other models (TSB 07-59-07R) which states that minor fogging is normal, but heavy condensation that forms puddles may be a warrantable defect.
Pro Tip: If your Limited or GT model displays an "SRH Disabled" warning after disconnecting the battery, lifting the car on a jack, or performing suspension work, the system may need to be recalibrated. A specific procedure involving turning the steering wheel and cycling the headlight switch may resolve the issue without a trip to the dealer.

Purchasing a used OEM headlight is an excellent way to save money, but careful inspection is key. Given the high cost of new units, a quality used assembly offers significant value.
- Verify the Part Number: This is the most crucial step. Ensure the part number matches your vehicle's trim (SRH vs. non-SRH). A headlight from a Limited will not work on a Premium. Check for OEM part numbers like 84002VC100 (non-adaptive) or 84002VC081/84002VC091 (adaptive).
- Inspect All Mounting Tabs: The plastic mounting tabs are essential for a secure fit. Ensure all tabs are intact and not cracked or repaired with glue. Broken tabs are common during removal if not done carefully.
- Check the Lens Condition: Look for deep scratches, rock chips, or stress cracks. Minor scuffs can often be polished out, but major damage cannot. Since these are late-model vehicles, yellowing or UV damage is less of a concern but should still be checked.
- Look for Signs of Moisture: Inspect the inside of the lens for a "tide mark" or dried mineral stains at the bottom. This is a clear sign the headlight had a seal failure and will likely leak again.
- Examine the Housing Seal: Check the seam where the clear lens meets the black plastic housing. Avoid any units that show signs of being pried open or resealed with excessive aftermarket sealant.
Replacement Overview
Replacing the headlight assembly on a 2022-2026 WRX is a moderately difficult job for a DIY mechanic. The primary challenge is that the front bumper cover must be removed to access the headlight mounting bolts.
- Difficulty: 3/5
- Estimated Time: 2.0 hours
- Tools Required: Phillips screwdriver, flathead screwdriver, 10mm socket, panel popper tool.
- Procedure: The process involves removing numerous push clips and screws from the wheel wells, under the front of the car, and in the engine bay to release the bumper cover. Once the bumper is off, the headlight is held in by three 10mm bolts.
Aiming and Calibration
After installation, the headlights must be aimed to ensure proper visibility and avoid blinding other drivers. The vertical adjustment is done using a long Phillips screwdriver to turn a gear mechanism accessible from the top of the headlight assembly. There are typically two adjustment points per headlight.
- Non-SRH (Base/Premium): Only manual vertical aiming is required.
- SRH (Limited/GT): While manual vertical aiming is the same, the SRH system may require electronic calibration if the assembly was replaced or if an "SRH Disabled" error is present. This can sometimes be done with a specific sequence of turning the ignition and headlight switch, but may require a dealer scan tool in other cases.
Cost Comparison
| Category | Estimated Cost | Notes |
|---|---|---|
| New OEM (Dealer) | $900 - $1,400 per side | SRH adaptive headlights are significantly more expensive. |
| New Aftermarket | $550 - $1,100 per side | Quality and fit can vary. Some offer different styling, like amber deletes or sequential turn signals. |
| Used OEM | $400 - $800 per side | Offers OEM quality and fit at a lower price. Condition is variable. |
| Shop Labor | $150 - $300 | Labor cost to remove the bumper and replace one or both headlights. |
Frequently Asked Questions (FAQ)
How do I know if my WRX has Steering Responsive Headlights (SRH)?
If you have a Limited or GT trim, you have SRH. An easy way to check is to look at your side mirrors; if they have integrated turn signals, your car is a Limited or GT and has SRH. Base and Premium models do not have this feature.
🎬 Watch: A complete breakdown of features across all WRX trim levels.Is a little bit of fog inside my headlight normal?
Yes, according to Subaru, minor fogging or misting on the inside of the lens that appears and disappears with changes in temperature and humidity is considered normal. However, if you see large water droplets, pooling water at the bottom of the housing, or streaks left behind after it dries, the headlight seal has failed and the assembly should be replaced.
Can I just replace the LED bulb if it burns out?
No, the main LED light sources for the low and high beams are integrated into the headlight assembly and are not designed to be serviced or replaced separately. If a primary LED fails, the entire headlight unit must be replaced.
Why did I get an "SRH Disabled" warning light?
This warning on Limited and GT trims can be triggered by several things: a fault in the headlight's internal motor, a problem with the vehicle's height or steering angle sensors, or a loss of calibration. It's common for this to occur after suspension work or even after disconnecting the vehicle's battery. Sometimes a simple recalibration procedure can fix it.
