On a dashboard, some typical brake lights that may appear are as follows:

This brake light indicates that there is an issue with your parking brake, or it is still engaged:
These lights represent various potential problems with your braking system. Because every car is unique, yours can have a different brake warning indicator than these. To be confident which light applies to your individual car, consult the Owner’s Manual.
*Note: Although your car’s ABS Warning Lights are specifically tied to the Anti-Lock Brake System, they can occasionally be connected to the hydraulic braking system.
The third brake light is not present.
America has required that all automobiles have a center brake lamp, sometimes known as a third brake light, that is situated above the left and right brake lights, as of 1986. A distracted driver is more likely to slow down the automobile if the car in front of him has a third brake light installed, according to a study. The third brake light, which is also known as a safety brake lamp or a high-level brake bulb, alerts other drivers when you apply the brakes. When other cars block their view of the left and right brake lights, it is helpful.
There is one more benefit to its existence. In our nation, red light from turn signals is permitted. Additionally, it may cause other drivers to become confused. However, adding a third brake light makes it much easier for them to see the location of the vehicle in front of them, especially at night.
Depending on the car, the third brake light is located in a varied location. It is typically fitted into the back glass of the car. It can be found in the deck lid of the vehicle. On some trucks, the spare wheel carrier may house the third brake light.

- Step 2: Remove the tail lamp assembly (if needed)
- Step 3: Remove the bulb.
- Step 4: Insert a replacement bulb after adding bulb grease.
- Step 5: Reattach the component (if needed)
- Repeat step 6 on the opposite side.
What does the Nissan Sentra’s brake light mean?
Bad Switch: A faulty or failed switch is a typical cause of the Parking Brake light remaining on. You may quickly verify this by jiggling the handle once it has been lowered. The switch is most likely to be the problem and needs to be replaced if the light goes out (or goes out and comes back on).
If the brake handle is not fully down, there is another factor that could cause the light to remain on. Verify again that the parking brake is released and that the handle is fully lowered. The light will remain on if the parking brake cable is under any stress.
Parking Brake Not Disengaging: Occasionally, the parking brake itself is the source of the issue rather than the switch or the wires. The dash warning light will remain on if the brake does not release when the handle is dropped.
Low Brake Fluid: Your Parking Brake light is a multipurpose device that is intended to turn on when the reservoir’s fluid level falls below a specific level. As the fluid level fluctuates, you might see the light turning on or off when making turns.
The brake fluid level sensor in your master cylinder is malfunctioning. It is sometimes integrated into the reservoir cap, and other times it is positioned on the side of the sensor. The Parking Brake light will come on if the sensor malfunctions or becomes faulty.
Uneven Fluid Pressure: If your automobile has uneven brake fluid pressure in one or more lines, it may influence how well it can stop and may even cause it to pull to one side or the other. The parking brake light in your dash can also be activated by it.
The brake light switch is what?
Your car’s brake light switch performs a crucial safety duty. The signal lights at the back of your car receive power when you depress the brake pedal, alerting other cars that you have slowed down.
The high mounted brake light is where?
Are there any more brake lights visible above your deck lid or back window? The high mount light assembly is seen there. It is a component of the brake light system on your car.
This part is known by a number of other names, including:
- assembly for a center high mount stop lamp
- assembly for a high mount stop light
- Cylindrical brake light
- assembled third brake light
- elevated stop lamp
In this discussion, we’ll refer to this component as a “high mount lamp assembly” for the purpose of clarity.
A lamp that is attached to the top of the rear window is known as a high mount lamp assembly. Together with the two brake lights on the back of the vehicle, it illuminates when you use the brakes. Like the other brake lights on the car, the lamp is red in color.
An Engaged Parking Brake
The parking brake sensor will signal the brake warning light to switch on if the parking brake is still engaged. The parking brake on your car should be entirely disengaged to prevent this from happening in most cases.
If you keep it the way it is, you’ll be using your parking brakes all the time, which can cause your brakes to overheat and hasten the wear of your brake shoes and brake pads.
The efficiency of your braking system may be impacted by the accelerated brake fluid deterioration brought on by these elevated temperatures.
Low Brake Fluid Levels
The amount of braking fluid in the system is monitored by a sensor in the brake master cylinder. The sensor will cause the brake light to illuminate if levels are below the minimal threshold.
Low brake fluid levels can be very concerning because they may be a sign of an urgent brake fluid leak.
Worn Out Brake Pads
As the caliper pistons must extend further to make contact with the rotor, worn brake pads might also result in a drop in brake fluid level, which can also activate your brake warning light.
This sensor wire makes contact with the rotor when the brake pads get too worn, which prompts the brake light (also known as the brake pad warning light) to turn on.
Anti Lock Braking System Malfunction
A brake warning light for the antilock braking system (ABS) is present in the majority of automobiles.
Both the brake warning light and the ABS light (if it has one) may turn on in response to issues with the antilock brake system. Electrical problems and even something as simple as a dirty wheel speed sensor can be the culprits.
Is it safe to operate a vehicle when the brake light is on?
There’s no need to panic if you’re driving along and the brake warning light comes on, or if it comes on and stays on after you press the brake pedal; your car has two separate brake hydraulic systems connecting the brake pedal to the wheels, so even if one of them fails, you’ll be able to stop it safely. Be mindful that if only one hydraulic system is used, it could not stop as quickly.
As carefully as you can, drive the car to a parking space or into the shoulder of the road, then gradually apply the brakes to bring the car to a halt. Make plans to bring the car to your preferred repair facility once it has been stopped safely and removed from the flow of traffic.
Is the installation of a third brake light required?
This is in response to your letter dated June 15, 1995, addressed to the Department of Transportation, in which you inquired about the legality of your “brake condition warning sensor” invention.
The third brake light flashes as a result of the sensor according to the rate of deceleration.
In accordance with Federal laws in the US, all stop lamps, including the third brake light (also known as the “center highmounted stop lamp” in our language), must burn steadily while in use.
Federal law forbids any manufacturer, dealer, distributor, or auto repair shop from installing the sensor to change the functionality of the third brake light and make it flash after the car has been sold.
However, the installation of the sensor by the car’s owner is not prohibited by federal legislation. In this case, it is necessary to check the law of the State in which the vehicle is driven to see if a flashing third brake light is allowed. We are unable to respond to inquiries regarding state laws. Write to the American Association of Motor Vehicle Administrators, 4600 Wilson Boulevard, Arlington, VA 22203, if you’d like their opinion on state legislation pertaining to flashing third brake lights.
Do we really need a third brake light?
After expanding Voevodsky’s experiment, the National Highway Traffic Safety Administration (NHTSA) came to the conclusion that “center high mounted stop lamps,” as the government refers to them, lessen accidents and injuries. As a result, the NHTSA started mandating third brake lights on all new vehicles in 1986. In 1994, the organization expanded that mandate to include all brand-new light trucks.
When the NHTSA plotted police-reported crash data from eight states, they discovered that the third brake lights reduced rear impacts by 4.3%. This indicates that since the lights became standard equipment, there have been roughly 200,000 fewer crashes, 60,000 fewer injuries, and more than $600 million in property damage saved every year—not to mention lives saved—despite being less striking than the original findings.
Recent studies have focused on the possibility that modern light-emitting diode (LED) brake lights may be superior to older incandescent bulbs at reducing the risk of rear-end crashes. According to preliminary statistics, LED lights could lessen collisions.
What is the price of a third brake light replacement?
For only the parts, aftermarket third brake light bulbs may cost between $50 and $250. Pricing is influenced by a number of variables, including brand, warranty, color or finish, light source, and set inclusions. Depending on local prices, labor could run you an extra $25 to $75.
Can LED brake lights be replaced?
Fortunately, they are simple to replace or repair on your own. Although LED tail lights are built to last, moisture may get inside worn housings and cause circuit boards to corrode, which would lead to the failure of the resistors.
Can you fix LED brake lights?
Due to their substantially longer lifespan and increased brightness, LED brake lights are increasingly the norm on new vehicles.
Either the strip or the full brake light unit needs to be replaced in order to repair an LED brake light.
Your dealership should be consulted first because your car is brand new. Your new automobile warranty may cover faulty components. Furthermore, there might be a recall on your car. In any case, the dealership would free of charge replace your brake light.
If you take your car to a dealership or repair facility, they will be able to determine if you need a new unit entirely or just the light strip. You can then choose your level of comfort from there.
The light strip should only be changed or the unit repaired if you have experience with electrical work. LEDs are frequently more sophisticated than an aftermarket LED bulb in an older vehicle, especially on newer models.
