Ensure full control of your Porsche’s lighting system with genuine and aftermarket headlamp switches from Design911. These essential electrical components control your vehicle’s headlights, fog lights, and sometimes dashboard illumination, ensuring optimal visibility and safety during every drive.
What They Are & What They Do
A headlamp switch — also known as a light control switch — is located on the
dashboard or steering column. It allows drivers to turn on, dim, or adjust
headlights, sidelights, and fog lamps, sending power to the correct lighting
circuits.
In modern Porsche models, the switch is integrated with electronic control
modules and automatic light sensors, ensuring seamless lighting transitions and
driver convenience.
Why They Fail
Over time, headlamp switches can suffer from electrical contact wear, internal
corrosion, overheating, or plastic fatigue. Common symptoms include flickering
lights, failure to switch between modes, or headlights not turning on at all.
Prolonged exposure to dust, heat, and vibration can degrade internal
connections and cause the switch to fail intermittently or permanently.
Why They Should Be Replaced
A faulty headlamp switch compromises visibility, safety, and road compliance.
Replacing a worn or broken switch restores reliable lighting control, ensures proper
electrical function, and eliminates dashboard warnings.

headlamp switches, designed for perfect fitment, OEM-level quality, and
