Dashboard lights that don’t operate while the headlights are on may be a common problem for drivers. Never fear. An extensive list of possible causes and solutions for dashboard light malfunctions is provided in this article..
As a driver, you have no other means of keeping tabs on the health and performance of your vehicle except what is displayed on the dashboard. The dashboard lights, for example, will show gas level, speed, dangers, engine health, oil pressure level, and other critical information about your car.. When you can’t see the dashboard at night, having these lights is a necessity.
Headlights, on the other hand, might cause dashboard lighting to malfunction and stop working. There are many reasons why dashboard lights may stop working, but the most common is an electrical problem.
There are many probable causes for dashboard lights not working when the headlights are on, including an alternator or battery failure, one or more dashboard LEDs that are dead, dim dashboard lights, and fuse problems.
A dying alternator or battery
To power electrical devices like dashboard lights, an automobile’s alternator must convert mechanical energy into electricity.
If this part fails, the dashboard LEDs will not be able to light up properly.. If the most powerful LEDs, such as the headlights, are using more power than the dashboard lights, this may be the case.
There may be some LEDs that don’t get the electricity they need since the battery’s lifespan has run out. Dashboard lights may go out when the headlights are turned on.
Dashboard LEDs dead
When the headlights are on, the dashboard may not have enough light if one or more of the LEDs have gone out. Putting on the headlights may drain a lot of power, thus the dashboard LEDs may not be able to light up.
Dimmed dashboard lights
When the headlights come on automatically, certain cars, particularly more modern ones, have a feature that dims the dashboard illumination.
Fuse fault
Fuse does an excellent job of preventing LEDs from being damaged or even blown up as a result of being overloaded by an electrical source. Fuse problems might arise, making it difficult to deliver current.
The dashboard light and other components connected to the fuse will be left without power if this occurs, which is especially problematic when the car’s headlights are on.
What are solutions to Dashboard lights not working when headlights are on?
Dash lights not working when headlights are on is a common problem, but it can be fixed. For your own safety and convenience, it’s important to maintain the health of your vehicle.
It’s important to keep an eye on your car’s dashboard lighting because you can see so much there. For example, you can monitor the health of your car’s engine, as well as its gas levels.
Nonetheless, to fix dashboard lights that don’t work when the headlights are turned on, you must first identify the root reason. Here are some remedies to the most common causes of dashboard lights not working when the headlights are on.
- Replace the alternator or battery if they have gone bad or old and put new ones
- Replace the dead dashboard light LEDs with new ones.
- If the dashboard lights go dim automatically when you power on the headlights, you can adjust the light button to feature dashboard readings for visibility.
- If the issues are coming from the faulty fuse, replace it with a new one to ensure enough current connection.
How can a driver Repair dashboard lights that are not working
If your dashboard light is malfunctioning, you can either fix it yourself or take the vehicle to a professional. If you want to accomplish it yourself, you can use the methods listed below.
- While testing the dimmer switch, insert the car key to its position and put on the headlights, then try to adjust the dimmer switch
- For the faulty fuses, check on the fuse boxes, remove and put the new fuse. Always ensure the battery connection is off when handling fuse issues.
- If the dashboard LEDs are the ones to be replaced, inspect them through the gauge cluster. By removing the gauge cluster’s trim, see whether its electrical connection to the LEDs is the problem or not. If the bulb has gone bad, take off the bulb socket and insert a new bulb.
Is this problem temporary? Can it be resolved by itself?
In fact, the dashboard lights won’t function properly if the headlights are on, thus the problem isn’t likely to go away. It’s a long-term problem that can’t be solved on its own.
For this reason, it’s necessary to replace or alter things like burned-out fuses, drained batteries, dimmed LEDs, and other automated dimming features.
Conclusion
For nighttime driving, dashboard lights are essential to let you see what you’re doing in your car clearly.
The dashboard provides information about your vehicle’s speed, petrol level, engine health, and more. There are exceptions, of course, when it comes to checking the dashboard lights. Replacement of the LEDs, battery, or fuses should be done.
