Headlight Fuse or Relay If a headlight fuse blows, it could cause the headlights to stop working. Most headlight systems are also designed with a relay that switches the power between low beam and high beam headlights. If this relay goes bad, it could allow power to the high beams, but not the low beams.

If the head lights took that long to turn off then you more than likely have a failure starting in the body control module. This is a common failure on this vehicle. I typically start by reprogramming the body control module. But if the issue persists, then I replace the body control module.

Most total headlight failures are caused by a bad component like a fuse, relay, or module. Wiring problems can also cause both headlights to stop working. High beam headlights don’t work or low beams don’t work. The cause: A burned out bulb, or a problem with the high beam switch or relay.

Reason #1: Blown Fuses or Bad Replays By far the most common reason your brights will stop working is from a blown fuse or a bad relay. Under the hood, a fuse box holds a variety of fuses and relays hooked up to all sorts of electrical components throughout your car.

More Illumination, Automatically The system uses a camera to continuously scan the road. When it’s very dark and there’s no traffic, the high beams come on automatically.

Even if your car comes with automatic headlights, that mode may not be selected as deafault. If they still do not work despite being in the AUTO position, then perhaps the sensor has stoped working correctly. It’s easy to test- with the headlights in AUTO position, cover the sensor with your hand.

Press and release the dome override button (near the headlight switch) four times within a six-second time-frame. Listen for a chime, which lets you know that the automatic headlight system has been disabled.

Please remember, daytime running lights (DRL) are a safety feature that can help make it easier for others to see the front of your vehicle during the day. If your vehicle is equipped with a “DRL OFF” setting, they can be turned off by twisting the headlight control knob to “DRL OFF.”

If the car is equipped with automatic headlights, then the head light switch will have an AUTO setting on the switch. If this setting is located on your light switch, then all you have to do is put the switch in this setting and the headlights will come on and go off automatically.

A: Not all vehicles have automatic headlights, especially older vintages. But I agree that, if your car is so equipped, you should use the automatic setting. Although there are not reminder lights on the dash indicating that the headlights are off, that task often falls to oncoming motorists who flash theirs.

There are two options available when adding automatic headlights: install a factory package or an aftermarket kit. If the car manufacturer supplied the accessory kit to retrofit the vehicle, the switch will be an original equipment unit with added functionality.

DRLs are lights located on the front of a vehicle that remain on whenever the engine is running. Unlike headlights, daytime running lights are fairly dim and don’t illuminate the road ahead. The purpose of daytime running lights is to increase the visibility of your car, so that other drivers can see you on the road.

If your vehicle is equipped with automatic headlights, they will be indicated with the word “auto,” or the letter “A” enclosed in an upside-down headlight. Tip: If your vehicle has fog lights, the symbol will be near the main headlight controls, but not in line with the other controls.
