The Important of Headlight

It is understood that relevant statistics show that 25% of the total vehicle mileage is at night or in the case of insufficient natural light, and 33% of the accidents involving personal injury occur in this case, and about 50% of fatalities occurred at night. From this point of view, the importance of headlights for our driving at night is self-evident.

Not all headlights do their work well. Evaluations show that the on-road illumination provided by vehicle lights varies widely.

Some new types of lighting technology show promise.Some new types of lighting technology show promise. High-beam assist increases high-beam use by automatically switching between high beams and low beams, depending on whether other vehicles are present. Curve-adaptive headlights pivot in the direction of travel to improve visibility on curvy roads.

Good headlights shouldn't cause excessive glare.  Properly aimed low beams light up the road ahead without temporarily blinding drivers of oncoming vehicles.  

As of October 2021, 29 percent of headlight systems tested on model year 2021 vehicles received a good rating. Almost half of the systems tested were rated marginal or poor because of inadequate visibility, excessive glare from low beams for oncoming drivers, or both.
