Low beam light provides short-range visibility without blinding oncoming drivers, while high beam light provides long-range visibility but can blind others.

• Low beam light is angled downwards to illuminate the road directly in front of the vehicle.

• High beam light is angled upwards to illuminate a longer distance ahead of the vehicle.

• Low beam light is used in normal driving conditions to avoid blinding oncoming drivers.
