OEM headlight manufacturer Hella has warned that the high light output of modern headlights has made proper alignment more critical than ever, as the issue of headlight glare continues to present problems for drivers.
With 25% of motorists reporting that they now drive less at night due to headlight glare and the problems it causes, with 5% saying they have stopped nighttime driving altogether, Hella is pointing out that even minor misalignments can have a significant impact on other road users.
“While brighter headlights improve road safety by enhancing visibility, improper alignment, the rise of higher-riding vehicles, and the intensity of advanced lighting technologies are contributing to driver discomfort and reduced confidence,” said Dave Clark, Lighting Product and Brand Manager at Hella. “It is vital to strike the right balance between illumination and safety.”
Help to prevent headlight glare
Independent garages have a critical role in addressing headlight glare by ensuring proper headlamp alignment during routine maintenance.
Misalignment caused by suspension issues, vehicle load changes, or improper installation can significantly increase glare for other road users. Hella emphasises the importance of using OE-quality bulbs, replaced in pairs, to maintain balanced performance and reduce glare-related issues.
The company also highlights the growing adoption of innovative technologies such as adaptive front lighting systems (AFS) and asymmetrical light distribution, which focus light on the road while minimising glare for oncoming traffic. “For these systems to perform properly, correct ADAS calibration is essential,” Clark added.
As public concern over headlight glare intensifies, Hella believes independent garages and parts suppliers are well-positioned to help motorists address the issue.
By prioritising high-quality, well-aligned lighting components and offering advanced lighting solutions, the sector can play a key role in improving safety and restoring driver confidence.
