Enhance safety and visibility with genuine and aftermarket
Porsche reverse light switches from Design911. This essential component ensures
your reverse lights illuminate automatically when engaging reverse gear,
alerting others and improving visibility while manoeuvring your Porsche.
What They Are & What They Do
A reverse light switch, also known as a back-up light switch, is a small
electrical sensor fitted to the gearbox or transmission housing. When reverse
gear is selected, the switch closes an electrical circuit, activating the
reverse lamps at the rear of the vehicle.
This function provides immediate illumination for safer reversing and signals
to pedestrians and drivers that your Porsche is backing up — an important
feature for both safety and compliance.
Why They Fail
Over time, reverse light switches can fail due to mechanical wear,
corrosion, internal short circuits, or exposure to transmission oil and heat.
Common symptoms include non-functioning reverse lights, flickering bulbs, or
lights staying permanently on. A faulty switch can also cause MOT test failures
or safety risks by making your vehicle less visible in reverse.
Why They Should Be Replaced
Replacing a faulty reverse light switch restores proper light activation,
visibility, and compliance with road-safety standards. A new OEM-quality switch
ensures accurate engagement, long service life, and reliable operation under
all temperature and vibration conditions.
At Design911, we offer genuine Porsche and premium aftermarket reverse light
switches compatible with both manual and automatic transmissions, ensuring precise
fitment and dependable performance for every model — from classic 911s to modern
Cayenne, Macan, and Taycan vehicles.
