Most newer cars can be set so the lights come on automatically when the car is started (mine will do that and it's 15 years old). Technology can't always save people from stupidity.

Many automatic headlight systems include the taillights.

You physically have to turn the headlight switch on to get the taillights to turn on. What other research would you like me to try?? Thanks.

FAQs: Do tail lights come on with automatic headlights?

Do tail lights activate when I use automatic headlights?

Yes, tail lights, the red lights at the rear of your vehicle, activate simultaneously with your headlights. This synchronization occurs whether you switch on the headlights manually or if they are set to operate automatically.

Are tail lights supposed to be on when the headlights are on?

When you activate the headlights, your vehicle’s tail lights should automatically turn on. Note, however, that while tail lights illuminate with the headlights, brake lights only activate when you press the brake pedal. Sometimes, brake lights may function even if the tail lights do not.

Is the headlight switch responsible for controlling the tail lights?

Indeed, the headlight switch controls the tail lights. However, remember that a separate fuse could also be specifically for the tail lights.

Do tail lights illuminate when daytime running lights are on?

No, tail lights do not turn on when daytime running lights (DRLs) are active. DRLs are designed to be less bright than headlights and are not intended for nighttime use. Typically, tail lights only activate when the headlights are on.

The position marked "AUTO" would turn on both the headlights and taillights automatically. There are sensors that determine when they are turned on based on the outside ambient light level. You just leave it there on "AUTO" all the time and it is not necessary to turn it off when you shut off the car.

You posted asking about why automatic lights (front and rear) aren't on any cars. Then after multiple people post that indeed they are common on the cars they own, you reply that you wish yours did that.

I go to the trouble to research your specific car, explain that you already have that feature, and how it works. After all of that, you say that you would rather just turn them on manually anyway. Thanks for wasting my time.

Was just pissed stupid people don’t have lights on in dangerous weather conditions. With your contribution i now know cars are equipped with the option to use safety lights, and just don’t, so again thank you.

turn them on or off.
I think many newer cars have that capability.
I had a rental recently that also automatically adjusted the lights depending on how dark it was. I loved that. Georgia has many dark roads with no street lights. It brightened on those dark roads, then went back to normal lighting when there was more light on other roads.
It would be nice if that was a standard feature.

Basically, the headlights were automatically always on whenever driving, and could not be turned off. Not the tail lights though.

Mon Dec 30, 2024, 05:45 PM

It has sensors that, when it sees that it's getting beyond a factory-specified "dark," automatically turns the headlights to full brightness and also starts the taillights. But if you want foglights you have to pull the knob toward you to get them to come on. I just leave the switch in Auto, it works fine.
