How to Turn Off Bulb Warning Light

Many modern cars come with pre-installed monitoring tools to assist drivers to figure out exactly what error may be happening with the car.

A specifically common one is car dashboard lights that indicate general issues with the car such as with the engine or bulbs.

Bulbs play a significant role for cars as signals for brakes, turn signals, and headlights. This means any driver should be aware of what bulb warning lights are, what they mean, and how to turn off bulb warning lights.

Bulb warning lights may indicate an error with a circuit or mean you need to replace a bulb that may be dead.

A bulb warning light may show you specifically which bulb or you may have to do a thorough check of the bulbs around your car to figure out where the issue is.

Until the issue is located and fixed, the bulb warning light will continue to show on your dashboard.

To turn off bulb warning lights, there are a few steps that will have you on your way.

5 Steps to Turn Off Bulb Warning Light:

Step 1: Look for Bulb-out Warning Light

The first thing a driver should look for is a bulb-out warning light on their dashboard. If you have it showing on your dashboard, then it may indicate that you may need to replace the bulb of one of your lights.

Some vehicle models offer a generic light bulb warning light showing that there is a bulb issue.

More sophisticated cars have tools to show exactly what bulb may have an issue for example the turn signal bulb.

If your car is not so sophisticated, you have the option to buy monitoring hardware that will specifically identify which light on your car may have a problem so that you can waste less time trying to figure out which one.

Step 2: Locating the Bulb Issue

If the car owner is not sure of the bulb with an issue, a thorough check of all the car bulbs will help you identify what may need fixing. This may include checking brake lights, turn signals, headlights, and fog lights.

Once the lights on the car with a problem are identified, you will need to check whether it is the bulb or circuit that may have signaled the warning light. Once the actual problem is identified, it is easy to figure out how to fix it.

Step 3: Options for Fixing the Bulb Issue

Fixing the light bulb or circuit can be done personally or by scheduling a service appointment with experts who will do it for you. It may need a bulb or circuit replacement.

If you do it yourself, you will have to unplug the bulb to replace it with a new one.

After fixing or replacing the bulb or circuit, the car computer will turn off the bulb error light or turn the bulb failure warning light off.

There are instances where the suggested fixes may not turn off these lights. This may mean you may need to reset the car computer.

Step 4: The Bulb Warning Light Did Not Turn Off

If the car computer fails to turn off the bulb error light after you have fixed any of the issues with the lights, it may need a reset. Resetting the bulb out warning light will need you to loosen the negative terminal of your battery.

This will disconnect the power to your computer.

After disconnecting power to your computer, you will need to leave this for about ten minutes to reset the light bulb warning light.

Step 5: Resetting the Car Computer

Once the ten minutes have passed, retighten the negative terminal. Once the computer is back on, check whether the warning light bulb reset. If it resets, it will turn the bulb failure light off.
