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.

I am reporting a severe and known thermal design defect regarding the factory LED headlight assemblies on the 2021 Land Rover Defender 110.The integrated Daytime Running Light (DRL) LED module has completely failed and burned out prematurely on my vehicle (Current mileage: 66,800). This is a well-documented engineering failure across the L663 Defender community, tracked internally by Land Rover under Special Service Message SSM 75479. The internal LED driver chip consistently overheats and destroys itself within the sealed headlight unit.Because this is a sealed component, Land Rover does not offer a replacement bulb or individual electronic module repair. Instead, consumers are forced to replace the entire headlight assembly at a cost of thousands of dollars out-of-pocket, as the vehicle is past its standard factory warranty.This is a critical safety issue. The loss of the daytime running light significantly reduces vehicle visibility to other drivers, pedestrians, and cyclists during daytime hours and adverse weather conditions. Furthermore, the complete unexpected failure of safety-critical exterior lighting elements creates an unnecessary hazard on public roads.Land Rover is fully aware of this thermal design flaw but has failed to issue a safety recall to update the defective cooling or electrical components within these headlamp assemblies. I request that the federal safety agency investigate this systemic lighting failure and mandate a manufacturer recall to replace these defective units before visibility-related accidents occur.

Driver Side Daytime running lamp illumination failed at 45 thousand miles. There is no internal notification of the failure and it failed prematurely. Its outside of the JLR warranty and they are not supporting any repair nor is the dealer who wants to replace both lamps at the cost of $6,000.

The left headlight daytime running light has died due to a defective chip in the light itself. It may cause a higher chance of a daytime wreck because of reduced visibility. Also, more chance of me getting pulled over for my headlight not working. Apparently it’s a common issue that JLR know about, but won’t do anything. Jaguar Land Rover (JLR) Special Service Message (SSM) 75479 relates to the premature failure or dimming of the Daytime Running Light (DRL) halo on premium LED headlights, most notably affecting vehicles like the 2020-2023 Land Rover Defender. SSM 75479 acknowledges the internal awareness of this condition for technicians, though it is designated as an informational service message rather than a formal recall.

Both daytime running lights failed simultaneously. Not covered by warranty and told that they would cost >$5,000 to repair. There have been hundreds of these reported and it should be a recall

The daytime running lights (DRL) have failed in the passenger side. After some quick research, it's apparent that this is a widespread issue with the "Signature" halo lights in the Defender headlamp assembly. Reddit discussion: [XXX] ) Here is a Youtube video showing the issue and "fix". So many people have had this same issue that this guy figured out the problem: [XXX] ) The original warranty would have covered it but my warranty just expired earlier this year and the extended warranty will not cover it. The dealership is telling me that the entire headlamp assembly will need trashed and replaced all because this small "chip" within the unit has failed. The cost to repair is close to $3,000. Seeing that the issue causes the DRL's to fail which could lead to a failed vehicle inspection, the issue should be reported more widely and a recall should be issued. Thank you for your time!

The halo headlight went out, and I have an extended warranty that supposedly doesn't cover it. After researching, this seems to be a national event. The headlights need to be recalled and the manufacturer needs to be held accountable.
