Brake Light Switch
There are no products in this section at this time
Ensure road safety and reliable lighting performance with brake light switches from Design911. These small but essential components play a critical role in your Porsche’s safety system — activating the rear brake lights the moment the pedal is pressed, warning following drivers that you’re slowing down or stopping.
What They Are & What They Do
A brake light switch is an electrical sensor mounted on or
near the brake pedal. When you press the pedal, the switch completes an
electrical circuit that illuminates the brake lights and may also signal other
vehicle systems such as cruise control or electronic stability management. A
properly functioning switch ensures instant brake-light activation and safe
communication with other drivers.
Why They Fail
Brake light switches can wear out over time due to repeated
mechanical use, internal corrosion, moisture intrusion, or electrical contact
failure. Exposure to dirt, brake dust, or heat can cause sticking, delayed
response, or total failure. When this happens, the brake lights may fail to
illuminate or stay on constantly, which can trigger dashboard warnings or MOT
test failures.
Why They Should Be Replaced
Replacing a faulty brake light switch restores safe
operation, prevents false warning lights, and maintains compliance with
road-safety regulations. A new, OEM-quality switch ensures precise pedal
response and dependable illumination, helping to protect you and other road
users.
