![]() ![]() That’s also the basic idea behind adaptive headlights, which swivel from side to side, or up and down, to adjust for curves or elevation changes. This automatic system is mostly for driving on rural roads or unlit highways where people often “overdrive” their headlights – travelling too fast for how far their low-beams illuminate ahead, so they can’t stop in time if something beyond their illuminated field of vision is on the road, such as an animal. As soon as other lights are detected, the system turns the high-beam headlights off, and then switches them back on again once the light disappears. The camera detects lights – not just oncoming headlights but also taillights of vehicles ahead, as well as streetlights or other illumination that indicates the driver is in the city and doesn’t need high-beams. ![]() ![]() The system uses a forward-facing camera, usually mounted in or near the rearview mirror. ![]() Most commonly, the driver leaves the high-beam switch on all the time and activates a second button for the automatic function. Like automatic headlights, the system is driver-selectable. At the same time, since they turn the high-beams on when the road ahead is dark, they can help drivers who don’t always think to switch them on even when they can provide more illumination down the road. They shut off the brighter lights as needed to avoid blinding occupants of oncoming vehicles. IIHS’ latest top safety standards give auto industry a rough rideĪutomatic high-beam headlights help solve two issues.Mandatory changes are coming that will require front and rear lighting, but not for another couple of years. Your daytime running lights will be on, of course, but very few of them also illuminate the rear lights that other drivers need to see you in rain or snow. Most don’t activate when it’s relatively bright but your lights should be on, such as when it’s raining, so be sure to switch them on manually in these situations. Most automatic headlights are set by the manufacturer, although some allow drivers to change the light sensitivity to how dark it must be before they’ll come on.
