The electrical switch that activates the brake lights is known as the brake light switch. The brake light switch makes contact when the brake pedal is pushed, and the brake lights activate.
The
brake lights and the button that triggers them are naturally vital to vehicle
safety since they inform the drivers behind you that you are slowing down.
During
a MOT testing
service, they are inspected for this safety reason. When the brake
pedal is pressed during the test, the brake lights should glow clearly.
When
the brake light switch fails, the vehicle normally exhibits a number of
symptoms that alert the driver to the issue.
1. Brake lights that stay
illuminated - This is one of the most frequent indications of a broken
brake light switch. If a brake light switch internally fails, the brake lights
may remain activated even when the brake pedal is not engaged. It is critical
to conduct an internet search for car services near me
and schedule an appointment for your vehicle to be examined and repaired by a
qualified technician. The brake lights will burn out faster than they should,
and the battery will be drained parasitically.
2. Brake lights that don't
work - Another sign of a faulty brake light switch is that the brake lights
aren't working at all. The switch will not be able to activate the lights when
the pedal is pressed, and the lights will not operate as a consequence. Look
for car mechanics near
me and book an appointment as soon as possible to have the faulty brake
lights investigated and necessary repaired completed.
3. Car won't start - Some
vehicles have keyless ignition. All you have to do to start the engine in these
automobiles is press down on the brake pedal. It's possible that your car won't
start because the brake light switch isn't sending a signal to the car's
computer indicating that the brakes are engaged. If this happens, contact a car
repair agency or a technician right once to have your brake light switch
replaced.
4. ABS warning light turns
on- Whenever the ABS light on your dashboard illuminates, it means
you have a problem with your anti-lock brake system. Low brake fluid, a broken
ABS control module, or a faulty brake light switch might all cause your ABS
warning light to turn on. When you apply the brakes, the brake light switch
sensor signals the ABS module in your vehicle that it's time to start the ABS
hydraulic pump. As a result, if your ABS warning light illuminates, it's
possible that your defective brake light switch is to blame.
5. Cruise Control
Deactivation - If your car has cruise control, a damaged or faulty brake light
switch might disable it. What causes this to happen? The cruise control system
and the rear brake lights are often controlled by the same switch in many cars.
As a result, if the brake lamp switch fails, your cruise control will most
certainly fail as well. This isn't to say that the cruise control stops
operating only due to a faulty brake light switch. It can also happen if the
electronic control module has a blown fuse or a faulty speed sensor. However,
it is always preferable to be safe than sorry. If your cruise control stops
working, have a professional look at your brake light switch too.
If
you use an online MOT
history checker, you'll see that one of the most prevalent causes for a
MOT test failure is a faulty light.
Since
brake lights are what alerts vehicles driving behind you that you are
slowing down or coming to a stop, if the switch that triggers them
malfunctions, the vehicle's overall safety is jeopardised.
As
a result, if you believe your vehicle's brake light switch is faulty or
malfunctioning, have the brake lights checked by a professional mechanic to see
if a brake light switch replacement is required.
When Should the Brake Light Switch Be Replaced?
Brake
light switches, unlike brake pads, are meant to last the life of your vehicle.
That
so, internal components within your brake switch might wear down with time,
especially if your car's brake lights are controlled by a plunger-style
mechanical switch.
Because
the brake light switch is such an important part of road safety, it's vital to
keep it in good working order.
Furthermore,
if your vehicle's push-button ignition switch fails to turn on, you may need to
repair it right away in order to keep driving.
