Land Rover Defender headlights problems

Filed Nov 6, 2026 · Lights · IL

I am reporting a suspected systemic safety defect involving premature failure of the integrated LED daytime running lights (DRLs) on 2020–2026 Land Rover Defender (L663) vehicles. The DRLs reportedly fail at relatively low mileage, frequently around 50,000 miles, during normal vehicle operation. The suspected cause is overheating and premature deterioration of the integrated LED driver electronics due to inadequate thermal management. The precise cause requires investigation. This failure eliminates an important daytime vehicle conspicuity feature, reducing visibility to approaching motorists, pedestrians, and cyclists, particularly during rain, overcast weather, and transitional lighting conditions. Some owners report no dashboard warning when the DRLs fail, potentially leaving drivers unaware of the malfunction. Jaguar Land Rover has known about this issue since at least 2021. Its Special Service Message SSM 75479 specifically acknowledges DRL failures on 2020–2021 Defenders and documents an engineering investigation. Similar failures have subsequently been reported by owners of later model years, suggesting a potentially unresolved design defect. Because the DRL electronics are integrated into the sealed headlamp assembly, dealerships generally require replacement of the entire assembly, costing approximately $3,000 per headlight or $6,000 for both. Land Rover reportedly provides goodwill replacements selectively while requiring other owners to pay out of pocket. I request that the federal safety agency investigate the entire 2020–2026 Defender population, examine JLR’s engineering records, warranty claims, component failure rates, and headlamp design revisions, and determine whether a safety recall and manufacturer-funded corrective action are warranted. This is a recurring failure of a factory-installed safety-related lighting system, not simply an ordinary maintenance or warranty concern.

I own a 2023 Land Rover Defender 110 X. The passenger-side daytime running light halo is completely inoperative. On November 2, 2026, an authorized Land Rover dealer inspected the vehicle and advised that the entire passenger-side headlamp assembly must be replaced. The quoted repair cost was approximately $3,255, plus applicable taxes and fees. The dealer also advised that the vehicle cannot pass Hawaiʻi’s required safety inspection because of the lighting failure. The original headlamp has not yet been replaced and remains available for inspection. There has been no crash, fire, injury or death associated with this failure. I believe the DRL has failed prematurely on a relatively new vehicle. Because the DRL is integrated into the sealed headlamp assembly, the failure requires replacement of the entire assembly rather than an individual bulb or serviceable lighting component. I am concerned that this premature exterior-lighting failure reduces the vehicle’s daytime visibility to other drivers and prevents the vehicle from passing its required safety inspection. I am submitting this complaint so the federal safety agency can document the failure and evaluate whether similar DRL failures are occurring in other Land Rover Defenders.

The front driver side daytime headlight failed. This part on this vehicle is sometimes called the halo. I am told that it is about a $3,000.00 repair. I don't think this part should fail so soon nor should it cost so much to remedy. It is available for inspection on request. The vehicle is less visible. I am taking it to the dealer for inspection on November 9, 2026, the earliest day available. There were no warnings that it had failed. I only noticed it when seeing the reflection of the vehicle.

The headlight-halo/daytime running has failed on the driver side headlight.

Filed Oct 19, 2026 · Lights · TX

Without warning, the driver's side front Daytime Running Light (DRL) signature halo ring suffered a complete electrical failure while driving. The low-beam projector and high-beam lamps continue to function, but the primary forward signature DRL element is completely inoperative due to what appears to be an internal circuit/LED driver board failure within the factory sealed headlamp housing. This malfunction compromises vehicle safety by significantly degrading front-end conspicuity and visibility to oncoming traffic, cyclists, and pedestrians during daylight hours, twilight, and inclement weather. It also creates an asymmetrical forward lighting profile that can confuse oncoming drivers regarding vehicle width and lane position. Prior to the failure, there were no warning chimes, cluster warning lamps, or diagnostic messages displayed on the instrument panel or infotainment screen indicating an exterior lighting malfunction. The failure was abrupt and total. The vehicle and headlamp component have been presented to an authorized franchised retailer for diagnostic verification and confirmation of the internal circuit failure. The vehicle and original headlamp assembly remain intact and are available for inspection upon request.

My 2023 Land Rover Defender 130 X Dynamic is less than four years old and recently passed its 50,000-mile new-vehicle warranty limit. A LED daytime running light (DRL) should not fail this early. The integrated front daytime running light "halo" LED module inside the sealed premium headlamp assembly failed and is completely dark. Low/ high beams and turn lights still work, but it's not a replaceable component; the LED module's built into the sealed housing, so repair at the dealer means replacing the entire headlamp, while 90% still functions, costing ~$3,000 USD. DRLs exist to make the vehicle more visible to other drivers in daylight, dusk, rain, and glare. A burned-out halo DRL makes the front of the vehicle look uneven and can be mistaken for a headlamp that is out. There is no dash warning or message when the DRL fails, so the condition can continue unnoticed. Other drivers may not see the vehicle as soon or may misjudge its position. Inoperable DRLs can also cause a failed state safety inspection. Reduced conspicuity increases crash risk for other road users. The local Land Rover dealership service center inspected the vehicle and confirmed the premature DRL/halo LED failure, and stated they have seen a surprisingly large number of these same premature burnouts require replacement. After reviewing the federal safety agency records, this matches a pattern already known to the agency and to Jaguar Land Rover (JLR) the federal safety agency’s TSB/SSM database includes Jaguar Land Rover Special Service Message SSM 75479 (the federal safety agency document MC-10199802-0001), titled “Front Daytime Running Light(s) Are Not Working / Intermittent Operation.” This is not ordinary wear because LED DRLs should last far longer than 3.5yrs; that widespread pattern, plus JLR’s own internal SSM asking dealers to return failed headlamps for engineering analysis, indicates a recurring manufacturing or design problem in the sealed DRL LED module—not random bulb wear.

The signature halo LED ring on the front headlight stopped working and has now failed completely, impairing headlight performance. Land Rover previously replaced one of these units when under warranty, but now refuse to fix the second one unless privately paid for (I am now out of warranty). This is a known and common issue and is clearly a safety concern and a consequence of a Land Rover design flaw. In my opinion, this should be a safety recall.

On my 2021 Land Rover Defender 110, the front Daytime Running Light (DRL) halo unit experienced a complete illumination failure due to an internal component defect. Because the LED DRL system is permanently sealed inside the headlamp assembly, replacing the failed light required a complete headlamp replacement costing nearly $3,000 out of pocket. Shortly after this initial repair, the DRL halo unit on the remaining original headlamp assembly experienced the exact same total failure. This is a known pattern defect across 2020–2023 Land Rover Defender models caused by internal heat degradation of the LED components (referenced in JLR Special Service Message SSM 75479). The failure of exterior daytime running lights significantly reduces daytime vehicle visibility to oncoming traffic and pedestrians, creating an unexpected safety hazard. Jaguar Land Rover designed an integrated lighting system where a minor internal LED failure renders the primary safety lighting inoperable and requires a nearly $3,000 unit replacement per side. Given the immediate back-to-back failure of both factory headlamps, this is a dangerous systemic component defect rather than standard wear and tear.
