What Auto High Beam Assist Delivers

Auto High Beam Assist (AHBA) transforms your JLR vehicle’s high-beam function into an intelligent, camera-driven system. A forward-facing camera monitors ambient light levels, oncoming headlights and preceding vehicle taillights in real time[reference:0]. When the system detects another road user, it automatically dips the main beam to low beam; once the road ahead clears, the system restores full high beam[reference:1]. The result is a smoother, safer night drive with less manual switch operation and lower driver fatigue.

We deliver AHBA as a genuine OEM-grade retrofit. The system integrates with your vehicle’s existing ADAS architecture, operates on the native 12V electrical network and preserves factory diagnostic and warranty integrity[reference:2]. No wiring harness cutting and no core ECU replacement are required for compatible vehicles[reference:3].

How the JLR AHBA System Works

AHBA relies on three core elements that we verify and configure during the retrofit:

• Forward-facing ADAS camera: We confirm the camera hardware (for example, part 8U1270 on Defender L663 platforms with a 60° field of view and 30 m detection range) is present and operational[reference:4].
• Headlamp control module: The system communicates with the LED or Xenon headlamp module (such as 8U1150 on applicable Defender builds) to command beam transitions[reference:5].
• Powertrain Control Module (PCM) / Body Control Module programming: We write the AHBA activation flag into the vehicle’s configuration file and, where required, flash the latest AHBA control map so the ECU recognises camera commands[reference:6].

After programming, we calibrate the forward-facing camera using JLR diagnostic equipment. This alignment step ensures the system reliably distinguishes between oncoming traffic, street lighting and ambient darkness[reference:7]. The system then self-monitors continuously, storing no fault codes during normal operation[reference:8].

Compatibility and VIN Verification

We support AHBA retrofits across a broad range of modern Jaguar and Land Rover vehicles, including:

• Range Rover L405 (2013 onwards)
• Range Rover Sport L494 (2013 onwards)
• Range Rover Velar L560 (2017 onwards)
• Range Rover Evoque L551 (2019 onwards)
• Discovery 5 (2017 onwards)
• Defender L663 (2020 onwards)
• Selected Jaguar XF, F-Pace, E-Pace and XE models

Many vehicles leave the factory with the necessary camera and headlamp hardware installed but with the AHBA software flag dormant[reference:9]. Our process activates that latent capability. Because compatibility depends on model year, existing camera specification, headlamp type and PCM firmware, we confirm every retrofit against your VIN before you book[reference:10]. Vehicles that already feature AHBA via a rear-view mirror module—such as part LR070786 or LR025168—typically require only configuration programming rather than hardware replacement[reference:11][reference:12].

Key Benefits of the AHBA Retrofit

Improved Night-Time Safety

The system reacts to oncoming headlights and street lamps faster than manual switching, reducing glare for other drivers while preserving maximum high-beam illumination when conditions allow[reference:13].

Reduced Driver Fatigue

Long night journeys no longer demand constant hand-to-stalk attention. AHBA manages beam transitions automatically, so you focus on steering, traffic and road awareness[reference:14].

Full OEM Integration

We program through JLR diagnostic platforms and update the Car Configuration File. The retrofit retains all original lighting functions, dashboard indicators and vehicle safety systems[reference:15].

Reversible and Warranty-Safe

Because we make no harness cuts and replace no core ECUs, the upgrade remains reversible and preserves your vehicle’s factory condition[reference:16].

Our Retrofit Process

1. VIN check: You send your VIN; we verify camera hardware, headlamp type, PCM firmware and existing ADAS configuration.
2. Parts confirmation: If hardware is missing, we supply the correct genuine JLR camera, mirror module or wiring terminals for your build[reference:17].
3. Programming: We connect JLR diagnostic equipment to the OBD-II port, enable AHBA in the vehicle configuration and flash the latest control software where applicable[reference:18].
4. Camera calibration: We perform the forward-camera alignment procedure so the system detects traffic and ambient light with factory accuracy[reference:19].
5. Functional test: We verify automatic high-beam dipping and restoration during an on-road test before handover[reference:20].
