Is the 3Rd Brake Light Supposed to Stay On?
Most vehicles have a third brake light mounted in the center of the rear window or high on the rear deck. It’s sometimes called a “center high-mounted stop light,” or CHMSL. The bulb in this brake light is usually brighter than the other taillights, and it comes on any time the brakes are applied.
The third brake light is required by federal law in the United States. Canada also has a similar requirement. The regulation was enacted to help make vehicles more visible from the rear, and thereby reduce accidents.
There are a few exceptions to the rule. Some older vehicles were grandfathered in and didn’t have to have a third brake light. Some very large vehicles, such as trailers and buses, may have an additional set of red lights at eye level that serve as both tail lights and brake lights; in these cases, there is no need for a separate CHMSL.
If your vehicle is missing its third brake light or if it’s not working properly, you should get it fixed as soon as possible. A broken or non-functional brake light could result in a ticket from law enforcement, and it could also make your vehicle less visible to other drivers, which could increase your risk of being involved in an accident.
What Causes Brake Light to Stay On?
There are a few different reasons that your brake light may stay on. One of the most common causes is a problem with the brake light switch. This switch is located near the brake pedal, and it tells the brake light to come on when you press down on the pedal.
If this switch is faulty, it can cause the light to stay on even when you’re not braking. Another possibility is a problem with one of the bulbs in your taillight assembly. If a bulb has burned out, it can cause the entire assembly to stop working properly.
You’ll need to replace any burnt-out bulbs to fix this issue. Finally, if your car has an anti-lock braking system (ABS), there may be a problem with one of the sensors or other components in this system. When ABS is activated, it sends rapid pulses of electricity to the brakes so that they don’t lock up during hard stops.
If there’s a problem with ABS, it can cause the brake lights to stay on constantly as well.
How Do You Reset a Brake Light Switch?
If your brake light is on, it’s a good indication that your brake light switch needs to be reset. Here’s how to do it: 1. Start by disconnecting the battery.
This will ensure that you don’t accidentally short-circuit anything while working on the wiring. 2. Next, locate the brake light switch. It’s usually located near the brake pedal or in the fuse box.
3. Once you’ve found the switch, use a screwdriver to remove the two screws that hold it in place. 4. With the screws removed, you should be able to pull out the old switch and replace it with a new one. Make sure to reconnect the battery before testing out your new switch!
