Headlamp Aligner: How Vehicle Beam Checks Work

A headlamp aligner is a workshop tool used to check or adjust vehicle headlight aim. It differs from a wearable head torch used for hands-free personal lighting.

Vehicle headlamp aim is checked with suitable equipment and according to the vehicle maker and inspection procedure. Incorrect aim can impair visibility or dazzle others, so use a qualified workshop if needed.

A wall method can provide a rough reference but does not replace a calibrated alignment check. Follow the vehicle manual and local inspection rules, or have a workshop set the beam.

No. An aligner is a measuring or adjustment tool; a levelling sensor is part of some vehicle systems that alter beam position.
