What This Product Does

The lighter installation provides cigarette-lighting operation and a connection for compatible 12V accessories. Located within the dashboard or centre console, it forms part of the vehicle’s interior electrical fittings.


Functions

  • Provides the lighter’s electrical contact connection.
  • Supports compatible accessory power connections within the lighter installation.
  • Replaces a worn or damaged interior electrical fitting.


Technical Details

  • Brand: OE Match; aftermarket replacement
  • Primary supplied reference: 99765210100A05. Additional supplied references: 99665210110A05 and 99665210300A01.


Symptoms of Fault

  • No heating response from the lighter.
  • Accessories receive no power or operate intermittently.
  • Plugs feel loose or lose contact when moved.
  • Corrosion, scorching or physical damage within the outlet.
  • Cracks or looseness around the surrounding housing.


Why Replacement Matters

Renewing a confirmed faulty component can recover normal lighter operation and dependable accessory connections. OE Match focuses on Porsche replacement applications, using original references and fitment checks to guide component selection. Inspect the socket, wiring and connections first: replacing the lighter will not resolve a separate supply fault.

FAQs

What should be checked before replacement?
Inspect the fuse, electrical supply, earth connection and socket contacts to establish where the fault lies.

Will it suit every vehicle listed?
Check the original reference and installed lighter arrangement, particularly the diagram production notes and M580 applications.

About Headlamp Switch

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.

At Design911, we offer a full range of genuine Porsche and premium aftermarket headlamp switches, designed for perfect fitment, OEM-level quality, and long-term reliability across all Porsche models - from classic 911s to modern Taycan, Macan, and Cayenne variants.
