Group B Headlamp Aim, Equipment and Conversions
Prepare headlamp test equipment, identify beam images, assess aim and apply current LED or HID conversion rules.
How to prepare for this year's assessment
Start with group and vehicle class, confirm whether a rule applies, follow the prescribed inspection or administration method, and classify only the evidence permitted by the live source.
Core concepts
Concept 1
Prepare headlamp test equipment, identify beam images, assess aim and apply current LED or HID conversion rules.
Exam cue: Identify whether the scenario belongs to Group A or Group B before selecting a manual.
Concept 2
Set up the vehicle and equipment correctly before choosing the beam criterion and interpreting the result.
Exam cue: Set up the vehicle and equipment correctly before choosing the beam criterion and interpreting the result.
Concept 3
Headlamp aim, equipment setup, beam image and halogen-to-LED or HID conversion are explicit 2026–27 subjects.
Exam cue: Use the source version and effective date that apply during the live 2026–27 training year.
Concept 4
Do not apply a remembered conversion rule without checking the current vehicle application and manual text.
Risk pitfalls and guardrails
Selecting the wrong beam pattern or aim limits after incomplete vehicle or equipment preparation.
Guardrail: Do not replace current manual wording with workshop preference, memory from an earlier year or an assumption based on appearance.
Treating workshop repair preference as the statutory MOT test outcome.
Guardrail: Do not replace current manual wording with workshop preference, memory from an earlier year or an assumption based on appearance.
Reproducing a sample answer without checking current application and evidence.
Guardrail: Use public examples to identify concepts only; the live source and current facts control the result.
Memory anchors
Prepare Before Project
Correct setup is part of the inspection evidence.
Identify the Beam
Choose the applicable beam image before measuring aim.
Current Conversion Rule
Use live manual wording for LED or HID conversions.
Group B Headlamp Aim, Equipment and Conversions: Source
Confirm the answer in the live DVSA guide, inspection manual or applicable special notice.
Group B Headlamp Aim, Equipment and Conversions: Sequence
Identify group and class, confirm application, use the prescribed method, then classify the evidence.
Group B Headlamp Aim, Equipment and Conversions: Annual Boundary
Keep the 2026–27 assessed topic allocation separate from live rule changes and earlier training years.
