Traffic safety during nighttime remains a critical concern, particularly for vulnerable road users such as pedestrians and cyclists. This study investigates the role of glare from headlamps and other artificial lighting as a contributing factor in traffic accidents using Swedish crash data from the STRADA database (2010-2024). A total of 549 injury-related accidents were identified as associated with nighttime glare. The analysis reveals that while glare-related accidents constitute a small fraction of overall traffic incidents (approximately 37 per year or 0.2% of all nighttime accidents), certain patterns emerge: collisions involving pedestrians carry the highest risk of severe outcomes, single-vehicle incidents are the most frequent, and wildlife collisions show the highest proportional link to glare. These findings indicate that, although uncommon, glare can contribute to serious accidents, particularly for vulnerable road users, and underscore the importance of appropriate headlamp usage and glare mitigation strategies during nighttime driving
