Product Information
Product Information

OE Match headlamp switch, intended for lighting-control repairs and classic Porsche restoration work.

Fits

  • Porsche 911 1965-69

Check fitment for your specific vehicle (model, year, engine) before ordering.

What This Product Does

The headlamp switch provides the driver's control for the vehicle's lighting circuits. Its electrical contacts make or break connections as the lighting setting is changed.

Functions

  • Provides manual lighting selection.
  • Switches electrical connections for the selected lighting setting.
  • Replaces a diagnosed faulty lighting-control switch.

Technical Details

  • Brand: OE Match.
  • Component: headlamp switch.
  • Supplied references: 90161321200, 91161302900, 91161302903, 91161302904, 91161302901, 91161302902.

Symptoms of Fault

  • Headlamps or sidelights fail to illuminate.
  • Some switch settings operate while others do not.
  • Lighting flickers or responds inconsistently.
  • Operation changes when the switch is moved or pressed.
  • Excessive warmth develops around the switch.
  • Connections show discolouration, corrosion or heat damage.

These symptoms do not establish that the switch is defective. Bulbs, fuses, wiring, earth connections and any associated relays should also be inspected.

Why Replacement Matters

Renewing a confirmed defective switch addresses worn contacts or unreliable selection of lighting functions. Any damaged terminals or wiring also need attention; replacing the switch alone will not correct a separate circuit fault. OE Match focuses on Porsche replacement applications, making reference and vehicle checks an important part of selecting the appropriate component.

FAQs

  • What should be inspected before replacing the switch?
    Check bulbs, fuses, electrical connections and earth points, including evidence of corrosion or overheating.
  • Why can operation become intermittent?
    Worn internal contacts or poor connections may behave differently with movement, vibration or temperature changes.
  • Could another component cause the same fault?
    Yes. Wiring faults and associated relays, where fitted, can produce similar symptoms. Diagnosis should identify the faulty component before replacement.
  • What if the connector is heat-damaged?
    Have the connector and circuit assessed alongside the switch so the underlying cause is addressed.
