Land Rover Defender L663 DRL Halo Short Circuit & Non-Working Repair

A common Land Rover Defender L663 headlight issue is DRL halo failure, where the driver-side halo does not illuminate and the outer daytime running lights switch off after a few seconds. This is often caused by an internal DRL short circuit, faulty LED components, or driver board failure, with diagnostic faults such as:

B10F411 – Right front position lamp short to ground
B10F4-11 – Right daytime lamp short circuit

The angel eye halo ring and DRL signature strip may also suffer from flickering, non-functioning LEDs, fading, or yellowing caused by heat damage and component degradation. Common symptoms include:

DRL halo ring not illuminating
Halo flickering or intermittent operation
Daytime running lights switching off
Yellowed or damaged DRL optic

At Elite Module Repair, our Land Rover Defender L663 DRL repair service restores failed signature lighting systems by replacing affected internal components with high-quality replacement parts, including:

DRL LED driver board
DRL optic (where required and confirmed before booking)

This service focuses on repairing the faulty components responsible for DRL failure. It does not include unrelated parts such as control modules, casings, breathers, or gaskets.

Our technicians provide professional Land Rover Defender L663 Headlight Repair services, carefully diagnosing DRL faults, LED failures, short circuits, and internal electronic issues affecting headlight performance. Every headlight unit is thoroughly inspected and tested to restore correct lighting function, reliable operation, and long-term performance.
