How do Subaru automatic headlights work?
Subaru vehicles are known for their innovative features, and automatic headlights are no exception. These headlights are designed to enhance safety and convenience by automatically adjusting to changing light conditions. In this article, we’ll explore how Subaru’s automatic headlights function and why they are a valuable feature for drivers.
What Are Automatic Headlights?
Automatic headlights are a smart lighting system that turns your vehicle's headlights on or off based on the surrounding light conditions. This feature eliminates the need for drivers to manually control their headlights, ensuring optimal visibility at all times. Subaru integrates this technology into many of its models to provide a seamless driving experience.
How Do Subaru Automatic Headlights Work?
The automatic headlight system in Subaru vehicles relies on a combination of sensors and software to detect ambient light levels. Here’s a breakdown of how the system operates:
- Light Sensors: Subaru vehicles are equipped with light sensors, typically located near the rearview mirror or on the dashboard. These sensors monitor the intensity of natural and artificial light in the environment.
- Automatic Activation: When the sensors detect low light conditions, such as during dusk, nighttime, or in tunnels, the system automatically turns on the headlights. Conversely, when sufficient light is detected, the headlights are turned off.
- Integration with Other Systems: In some Subaru models, the automatic headlights are integrated with the windshield wipers. For example, if the wipers are activated during rain, the headlights may automatically turn on to improve visibility.
Benefits of Subaru Automatic Headlights
Subaru’s automatic headlights offer several advantages for drivers:
- Enhanced Safety: By ensuring that headlights are always on in low-light conditions, the system improves visibility for both the driver and other road users.
- Convenience: Drivers don’t need to worry about manually turning their headlights on or off, reducing distractions and simplifying the driving experience.
- Energy Efficiency: The system prevents unnecessary use of headlights during daylight, conserving battery power and extending bulb life.
Tips for Using Subaru Automatic Headlights
To get the most out of your Subaru’s automatic headlights, keep the following tips in mind:
- Ensure the light sensor area is clean and unobstructed to allow accurate detection of light levels.
- Familiarize yourself with the headlight control settings in your vehicle to understand how to switch between automatic and manual modes.
- Regularly check your headlights for proper functioning and replace bulbs as needed to maintain optimal performance.
Conclusion
Subaru’s automatic headlights are a testament to the brand’s commitment to safety and innovation. By automatically adjusting to changing light conditions, these headlights provide drivers with peace of mind and a more enjoyable driving experience.

Frequently Asked Questions
What is the difference between adaptive headlights and automatic headlights?
Adaptive headlights take automatic headlights a step further by adjusting the direction and intensity of the light beams based on various factors such as vehicle speed, steering angle, and road conditions. These systems aim to provide optimal illumination in all driving scenarios, enhancing safety and visibility.
Are automatic headlights always on?
Automatic headlights use light sensors, usually found on the dashboard or the rearview mirror, to see how much light there is outside. When the sensors see that the light has gotten low enough, the headlights are automatically turned on. On the other hand, they will turn off when there's enough light.
What are the disadvantages of adaptive headlights?
Adaptive lights also tend not to be repairable if something goes wrong, being sealed units that need replacement if they develop a fault, or are damaged by a loose stone, for example. Given the cost of these systems, a replacement outside of warranty could be painfully expensive (think £1,000 plus).
Does auto headlights drain the battery?
Key Takeaways
Leaving headlights or interior lights on can drain your car battery completely, especially if your vehicle doesn't have an automatic shut-off feature. Parasitic draws, such as interior lights, door lights, or faulty relays, can drain the battery even when the car is off.
How do automatic car headlights turn off circuit?
Automatic headlight switcher circuit
The circuit is built around timer NE555 (IC1), light-dependent resistor LDR1 and some discrete components. Potmeter VR1 is used to set the light sensitivity of LDR1.
How do automatic car lights know when to turn on?
Automatic lights have a sensor mounted on the dash or on the rear view mirror that detects darkness and it turns the lights on.
Why are my headlights not coming on automatically?
The likely cause is a fuse, headlight relay, headlight switch, dimmer switch or a wiring fault. About the only cause that is an easy fix is a blown fuse. Consult your owner's manual to locate the main fuse for the headlight circuit and replace that fuse with one having the same amp rating.
Does leaving your headlights on auto drain the battery?
Key Takeaways
Leaving headlights or interior lights on can drain your car battery completely, especially if your vehicle doesn't have an automatic shut-off feature. Parasitic draws, such as interior lights, door lights, or faulty relays, can drain the battery even when the car is off.
How do stop lights know when to turn on?
One of the most common ways traffic lights sense vehicles is through inductive loop detectors. These are coils of wire embedded into the road surface. Usually in the shape of a rectangle or square
What triggers automatic headlights?
The automatic headlight control function detects brightness outside the vehicle with an illuminance sensor installed near the dashboard, in order to control when the lights turn on and off. It turns on headlights when the amount of light picked up by the illuminance sensor drops below a certain level.
