As you probably know, high-beam headlights are very useful when driving at night. They allow you to see further ahead, and they also make it easier for other drivers to see you. However, they can also be a bit of a nuisance if you forget to turn them off when there's oncoming traffic. That's where Toyota's auto high-beam feature comes in.

How it works

Toyota's auto high-beam system is pretty straightforward. It uses a camera mounted on the windshield to detect when there's oncoming traffic. When it detects an oncoming car, it will automatically switch the headlights to low beam. Once the oncoming car has passed, it will switch back to high beam.

The benefits

Obviously, the biggest benefit of this system is that it takes the hassle out of remembering to turn your high beams on and off. It also has the potential to improve safety, since it's likely to result in fewer instances of drivers forgetting to turn their high beams off.

What speed does Toyota automatic high-beam work?

The High Beam Assist system works at speeds of more than 34 km/h. The device's performance will be limited by factors like a dirty windshield, changing weather, lighting conditions, and hilly terrain, so the driver must manually turn it off. Please consult, your local Toyota Dealer or Owner's Manual for additional information.

Are automatic high beams worth it?

Adaptive driving beams, which use near-infrared light to assist drivers spot approaching traffic and prevent collisions, are another feature of adaptive headlights that consumers should be aware of. Near-infrared lights create a bright beam around other cars but a dimmer one directly on them, enhancing visibility without dazzling other drivers. Some systems are superior at reducing glare than others, and the price for this feature varies.

Best bulbs for high beam

There are a few different types of high-beam bulbs, but the two most popular are HID (high-intensity discharge) and LED (light-emitting diode).

HID bulbs are generally more expensive than LED bulbs, but they're also brighter and have a longer lifespan. If you do a lot of night driving, HID bulbs are probably the way to go.

LED bulbs are a good choice if you're looking for a high-beam bulb that's more affordable and has a slightly shorter lifespan.

No matter which type of high-beam bulb you choose, make sure to get one that's specifically designed for your car. Different cars have different sized headlight housings, so you'll need to get a bulb that's the right size. You should also make sure to get a high-beam bulb with the same wattage as the original bulb.


Toyota's auto high-beam system is a convenient feature that can make night driving safer and easier. It's important to note, however, that the system is not foolproof. Be sure to clean your windshield regularly and keep an eye out for oncoming traffic, even when you're relying on the high-beam assist.
