The Defender DRL Problem

The Defender L663 has a known DRL defect. The LED board inside the sealed headlight degrades, causing the halo rings to turn yellow, go dim, flicker, or fail. It affects both standard and matrix headlights.

We repair the root cause — the faulty DRL PCB — inside your existing headlight. No replacement needed. Opened, repaired, resealed, and fully tested.

Can Defender DRL lights be repaired?

Yes. Most Defender L663 DRL faults are caused by a failing LED board (PCB) inside the headlight. This can be repaired without replacing the whole unit, typically from £300.

How much does Defender DRL repair cost?

Postal repair starts from £300. Mobile repair and fitting, where we come to your location anywhere in the UK, starts from £400. Both include DRL PCB repair, resealing, and testing.

Why are Defender DRL halo rings turning yellow?

The LED board inside the sealed headlight degrades over time, causing the DRL halo ring to discolour from white to yellow. It is a known manufacturing defect on the Defender L663, not caused by driving conditions.
