Why Did My Dashboard Lights Go Out While Driving 

Dashboard lights are always an integral part of safety; moreover, they are indicators, but have you ever thought about what happens if they stop functioning? If not, let it be like you are out on the battlefield without any shield. Yeah, if your dashboard lights go out while driving, you are not equipped to face the potential damages. You won’t get any updates about your vehicle or components, and it is essential to keep it on to alert you. 

Dashboard flickering is not something we can avoid because it’s dangerous to drive with a faulty dashboard, and it may leave us with no chance to prevent potential troubles that we may encounter. Dashboard lights are warnings, and without any signs, the probability of accidents increases.

Symptoms and Signs of Bad Dashboard Lights

Identifying faulty Dashboard Lights may seem troublesome, but it doesn’t bother me much. There are some symptoms through which we can identify the issue quickly:

• Lights flicker or flash: The easiest way to identify a faulty dashboard is to check whether your warning lights go on and off consecutively without any trigger. If so, your dashboard is dysfunctional.
• Lights stay on continuously: Even after troubleshooting or without any reason, if your warning lights stay on, this might be because of a faulty dashboard system.
• Illuminated warning:  If any of your warning lights are illuminated without any particular issues, then it indicates faulty dashboard lights.

Common Causes of Faulty Dashboard Lights

As I said before, the dashboard is an integral part of vehicle safety, and it must be in good condition. But there are specific reasons that interfere with the functioning of dashboard lights; the culprits are described below:

A. Electrical Issues

Electrical issues play a vital role in faulty dashboard lights, and there are various electrical issues, such as :

•  Loose connection: A loose connection means intermittent power supply, which leads to flickering lights. When there is a loose connection, every component powered by an electric current may face this time flashing. Dash lights are one such component.
• Faulty alternator: The alternator is the primary power source of every vehicle’s electrical system. If your alternator is not functioning correctly, it won’t charge the battery, and therefore, the power supply to different components will be altered. This may lead to a faulty dash light.
• Weak or dead battery: Even if your alternator supplies electricity, it has to pass through the battery, and if it’s dead or weak, it possibly affects the supply to different components, especially to the battery.
• Wiring issues: corroded or improper wiring may also lead to flickering dash lights.

So, there is every chance that if your dash lights flicker, it may underline some issues with your major electrical components.

B. Sensor Malfunctions

Sensor malfunctions can trigger dashboard lights go out while driving; this happens when a sensor fails or detects an issue, and it includes:

• Malfunctioning ABS sensors:  If your ABS sensor is faulty, it may illuminate or flicker the ABS warning lights in the dashboard.
• Faulty oxygen sensor:  If your oxygen intake is malfunctioning, your warning lights, that is, the check engine light, may flicker or continuously illuminate, indicating the issue.
• Ignition system issues: If your check engine lights flicker before you start your vehicle, it may represent an issue with the ignition sensor.

C. Computer System Problems

Problems with the vehicle’s computer system can lead to erratic dashboard light behaviour as they control so many other parts of your vehicle. Malfunctioning in any of the computer systems can affect the drivability as well as may be annoying by flickering your dashboard lights. These problems include:

• Faulty ECM/PCM (Engine Control Module/Powertrain Control Module): ECM or PCM are central components of your vehicle, and any problem with these parts may illuminate your warning lights along with many other symptoms.
• Software Glitches:  Software glitches are a crucial problem that may affect the total functioning of your vehicle, and these may lead to flickering warning lights.

What to Do When Dashboard Lights Go Out While Driving 

Flickering or constantly illuminated dash lights may be a headache for drivers. Moreover, it might fright you. But don’t get panicked; do take immediate actions to secure yourself and not cause any obstruction for others.

 Here is a list of actions to take when experiencing this issue:

1. Stay calm and avoid panic: The first thing you can do is to stay calm and composed when you encounter such a situation, realise the potential damages, and make necessary steps quickly. This might avoid the potential issues.
2. Check if other essential systems are affected: Soon after, you have to check whether any of your essential components, like the alternator, battery or sensors, are at risk.
3. Safely pull over if necessary: If you doubt the dashboard lights as notifications of any serious trouble, safely pull over for further check–up.

Troubleshooting

Flickering dash lights can make your drive worse as well as frighten you, so it is better to avoid such instances than risking your essential safety component. Here, I offer step-by-step instructions for drivers to diagnose the problem, including:

• Inspecting the dashboard lights: They are the most essential safety component, and regularly check them to ensure proper maintenance.
• Checking for loose wires and connections: Loose wiring circuits are another reason for faulty dashboard lights, so kindly check for connection issues regularly and fix them appropriately.
• Verifying sensor functionality: Sensors are a crucial part of your vehicle that plays an inevitable role in updating you about the working of different essential components, so make sensor verification a part of your routine monitoring.
• Check the Battery: The battery is the power source of every gadget, so for vehicle batteries, to safeguard your battery, regularly inspect battery terminals and ensure your battery is working correctly and there is no evidence of draining.
• Inspect the Alternator: The alternator is the power hub of your vehicle’s electrical component and primary power supply source. The alternator must be in good condition to power other features, so regularly check your alternator and ensure it supplies the correct voltage to power different parts.
