Brake Light Bulb Fault – (Troubleshooting and Fixes)

The vehicle’s brake light constitutes an essential safety feature that must be operational. Your braking lights are designed to flash brightly whenever you touch the brake pedals, alerting vehicles behind you that your automobile is accelerating down or that it’s coming to a stop. The ‘Brake Light Bulb Fault’ notice appears when the braking lights malfunction or flicker.

This message of error may have previously plagued you. If so, you’re not the sole individual who’s had to deal with this issue. It will be brought on by a number of issues that we’ll outline in this quick guide. So let’s get started.

Brake Light Bulb Fault: What is it?

Any problem with the ABS system that results in the vehicle’s back lights turning out is referred to as a “brake lamp bulb fault.” An alert light will then turn on in the control panel in this situation. It suggests that there is a brake system issue.

If you notice this lamp on while driving, pull over somewhere secure and examine the automobile. It’s possible that the vehicle’s engine has stopped or the brakes have failed. In a nutshell, the light on the brake button is a safety device that alerts the operator of a car to potential brake system problems.

How to Identify a Failed Brake Light?

The fact that the braking light isn’t functioning is undoubtedly the most obvious symptom that it is malfunctioning. The possibility of the light bulb beginning to dim is also present.

Your car won’t suddenly lose all of its brake lights, except if there is a significant issue with it. Most likely, just one set of them will depart.

When all of your brake lights suddenly stop working, you should probably visit a repair. This is a really major problem.

When your car is more recent, it could also feature a brake light failure signal that you can use to alert you to the problem. This will appear on the dashboard of your car.

Which are the Reasons for the Problem with the Brake Light Bulb?

Error-prone Brake Lights

Whenever bulbs get old, they often start to lose their dazzling light, get dull, and, in the majority of cases, eventually burn out. Therefore, the brake indicators would stop shining after the bulbs had reached the end of their practical use or lifespan.

Unreliable Brake Lever

Our automobiles automatically turn on the back headlights when we step on the brakes. Near the end of the brake foot is an illuminated brake button that activates the rear lights when we push the pedal. The ABS indicator will illuminate if the toggle switch isn’t operating properly.

Fuse Blows

A blown fuse is yet another potential reason why this warning is appearing. Our automobiles’ brake lamp bulbs are controlled by fuses. The fuse could not be operating if the toggle switch, as well as the brake lamp, were not malfunctioning.

Relay or Module Fault

Rear brake lights that aren’t correctly operated by a brake switch might lead to brake failure. Such errors can cause push-start automobiles’ engines to shut off. The anti-lock braking warning indicator on the dashboard may also begin to flicker as a result of this problem.

The Brake Control Cylinder’s Hydraulic Fluid Level is Low

The pump forces the insoluble fluid in the pneumatic brake line whenever the brakes are engaged, bringing the car to a halt. The brake indicators won’t illuminate if the hydraulic fluid levels are low since the foot pedals won’t have sufficient pressure to operate.

Wiring Issues

The proper operation of the brake lamps may be compromised by a wire that is cut, burned, or has a loose connection.

How Can the Brake Bulb Malfunction Warning Light be Fixed?

Poor Bulb

Change it out for a new one.

Poor Brake Switch

The technician should fix it.

Fuse Blows

• Put a fresh fuse in place of the burned one.
• Stop the engine of your vehicle to avoid receiving an electric shock.
• Track down the fuse box.
• Identify the blown fuse.
• Put the new fuse in its position.
• Verify that the issue has been resolved.

Wiring Issues

A broken wire can be fixed in three different ways.

Replace It

If you removed the clear covering as well as the metallic wires are exposed, tape it.

If the connections between the wires are slack, tighten them.

The primary cylinder has a low supply of braking fluid.

By topping off the fluid in the brakes to its proper level, we may resolve this issue.

Defective Module or Circuit

To determine if the brake circuit is functioning or not, it requires a multimeter. As a result, if the current one is beyond repair, we are able to substitute it.

How to Replace the Brake Light Bulb on your Own?

Here are the materials needed to replace the brake light bulb.

• Bulbs for the brakes.
• Heads of Phillips screwdrivers with flat heads are also used.
• Flashlight.
• Gloves.

Determine which light is malfunctioning first. After starting your car, turn on the parking brake lamps in order to inspect the lights, and shuffle to the rear of your car.

The lights won’t turn on, either one or both. After determining which direction it is, switch off your car and unlock the trunk.

The plastic covers must be taken off in order to get to the stop light. You’ll need to take off the floor covering obstructing the trunk first since it could be blocking the way of travel. A flathead screwdriver is required to pry the lids apart.

Disconnect any nuts or screws which were concealed behind the covers after the covers have been taken off. We can now take down the obstruction and get to the lightbulb. It varies depending on the manufacturer and type of your car and how you get at the lightbulb.

Although other cars just enable the obstruction to be withdrawn and need you to place your hand within the light fixture to take out the bulb, certain vehicles enable you to dismantle the complete rear light by simply removing a few screws.

Unplug the circuit breaker before relocating the lightbulb, as the brake indicator will still get a very little amount of power from it. Now detach the bulb as well as replace it by removing the plug from its mounting. After that, put the bulb down into its mounting by sucking it in.

After re-establishing the electrical relationship, assemble the stop light once again. But prior to you replacing the fasteners and cover flaps, make sure that you check it.
