Ford Explorer Brake Lamp Bulb Fault
Updated:
Have you received a brake lamp bulb fault message on your Ford Explorer and are wondering what to do? You have come to the correct place.
In the sections that follow, we will go over how to access the brake light bulb on your Ford Explorer, as well as other possible causes of this error message.
What is the Brake Light Bulb?
The brake light is a safety feature present in all vehicles. When you use the brakes on your Ford Explorer, the brake lights in the back illuminate, alerting other drivers that your vehicle is slowing or coming to a complete stop.
Common Brake Light Problems and How to Solve Them
Car brake light problems need not be perplexing. Several recurring issues make it easier to diagnose why a vehicle's brake lights are not working. Here are four common challenges that trigger brake light issues and how to resolve them.
Burnt Out Bulb
A burnt-out bulb is one of the most common brake light problems. Given the frequent use of brake lights, especially in older vehicles with traditional bulbs, they tend to wear out over time.
While newer models may use longer-lasting LED lights, older vehicles often require the replacement of traditional bulbs. This is a simple and cost-effective task that can be accomplished with basic tools.

Bad Brake Light Switch
When the brake pedal is pressed, it activates a switch that signals the rear lights to illuminate. Analog switches can wear out or become dirty over time, affecting their ability to make proper contact and transmit the correct signal.
Replacing the switch is a relatively simple task, and mechanics can easily test and address brake light problems related to the switch.
If all three brake lights go out simultaneously, it is less likely that all three bulbs failed at once, making a faulty brake light switch a more probable cause.
Blown Fuse
If the brake lights on both sides fail to illuminate and the brake light switch is functioning correctly, the next step is to inspect the brake light fuse. Find your vehicle's fuse box, typically located under the hood or on the kick panel inside the passenger compartment.
Refer to the fuse diagram on the box's cover or in the manual to locate the fuse for the brake circuit and ensure it is not blown. If the fuse is blown, replace it with a fuse of the same resistance.

Bad Socket
If a single brake light is not working despite a functional bulb, the next step is to inspect the light socket. Common brake light problems may include a socket with dirty or corroded connections or wiring that has worn out, leading to intermittent connections.
Replacing a socket is a straightforward process, involving snipping the old wires and splicing in the new unit, typically available at an affordable cost.
Keeping these tips in mind will make it easy to diagnose and address most brake light problems. If you prefer a hands-off solution, the experts at your local NAPA Auto Care are always ready to solve your brake light issues.
How to Test Your Brake Lights
To avoid unwarranted surprises from a false brake warning light, it is essential to periodically test your brake lights and warning system.
Performing this test twice a year, especially before the winter months when low light is prevalent, is recommended. Here is a simple method to test your brake lights:
- Have a friend stand behind your Ford Explorer.
- Depress the brake pedal.
- Have your friend check if all the brake light bulbs are working.
- Check the operation of all brake lights in your car, including those in the back, the center of the rear windshield, and other areas in the back.
- If you are driving alone, utilize a huge mirror in the back of your car that is visible from the driver's seat.
How to Fix Brake Warning Light Issues
Addressing brake warning light issues in Ford Explorer vehicles is generally straightforward due to accessible components. For instance, if a blown fuse is the cause, simply isolate and replace it with a new fuse of similar specifications.
In the case of a low brake fluid level, topping up the brake fluid resolves the issue. However, certain problems are best handled by a professional mechanic. Here are some of these issues and their respective solutions:
Release the Parking Brake
If a parking brake issue is the culprit, the solution depends on the type of parking brake in your Ford Explorer. If it is a matter of accidentally leaving the parking brake engaged, releasing it will reset the warning light.

However, if a malfunctioning parking brake is the cause, consulting a qualified mechanic is necessary for a thorough examination. The issue could be a loose or non-functional parking brake cable, and if so, the damaged part needs replacement.
Allow a Mechanic to Address the Sensor Problems
Parking brake sensors play a crucial role in your braking system, activating the brake warning light to signal when brake pads are wearing thin.
When these sensors malfunction, they may fail to provide timely warnings or trigger false alarms. Due to their sensitivity, addressing issues with these sensors is best left to a qualified mechanic. Attempting to fix or replace them without sufficient knowledge can lead to complications.
Is it Safe to Drive with an Active Brake Lamp Bulb Fault Warning?
It is not safe to drive if your car's brake warning light is lit. This warning signifies a braking system failure, and driving without a properly working brake system is hazardous.
When the brake pedal is squeezed, hydraulic brake fluid is used to increase force, allowing the vehicle to slow down. When the brake warning light illuminates, it indicates that the braking system may be malfunctioning.
While the brakes may not have totally failed, fast intervention is required. Park your car in a safe spot, come to a complete stop, and seek assistance.
Ignoring this warning and continuing to drive may result in serious repercussions, including an accident. It is preferable to err on the side of caution and handle the problem as soon as possible by asking for assistance.
