If you thought the had a problem with headlights on , wait until you see the results of new tests on small SUVs. Letís just say theyíre even less impressed with them. (By the way, the IIHS plans to test pickups next.)
IIHS researchers recently tested headlight performance on 21 small SUVs. Not one of them earned a good rating and only four of them came out with an acceptable rating. That means two-thirds of them received a poor rating.
IIHS engineers evaluate headlights on the Vehicle Research Centerís track after dark. A special device is used to measure how far the light is projected as the vehicle is driven on five approaches: traveling straight, a sharp left curve, a sharp right curve, a gradual left curve and a gradual right curve.
Glare from low beams for oncoming drivers is also measured in each scenario. A vehicle with excessive glare on any of the approaches canít earn a rating higher than marginal.
Headlight performance in todayís vehicles varies widely. The IIHS says thatís because government standards are based on lab tests and not real-world driving situations.
The other thing IIHS researchers point out is that price doesnít matter. A more expensive car doesnít mean you get better headlights. Itís a point they made when testing midsize cars earlier this year as well. .
Whatís also interesting is that the IIHS says modern lighting, like high-intensity discharge (HID) and LED lamps, along with curve-adaptive systems, also are no guarantee of good performance.
ďManufacturers arenít paying enough attention to the actual on-road performance of this basic equipment,Ē says IIHS Senior Research Engineer Matthew Brumbelow. ďWeíre optimistic that improvements will come quickly now that weíve given automakers something to strive for.Ē
For 2017, vehicles will need good or acceptable headlights in order to qualify for the Instituteís highest award, TOP SAFETY PICK+.
