First-ever IIHS headlight ratings show most need improvement

I think this rating category is overdue. It isn't as essential as crash test safety is, but there are many vehicles that cause blinding glare. Or, they just don't illuminate enough.

I hope the vehicle manufacturers pay attention.

The Toyota Prius V is the only rated vehicle to earn a "Good" rating from the tests.

It's great to see the methods they are using to test. I hope this leads to improvements in the future, like the small overlap crash test did.
