- Porsche 914 (1970-1976)
The OE MATCH Bulb Socket for Speedometer an original-style replacement component designed to restore the electrical connection and bulb mounting arrangement within the speedometer of selected Porsche 914 models.
Fits:
- Porsche 914-1,8V/1,8
- Porsche 914-2,0
Also known as a speedometer bulb holder, dashboard bulb socket or instrument illumination socket, this component forms part of the vehicle's original instrument lighting system.
The Porsche 914 features a distinctive driver-focused dashboard with individual instruments that provide essential driving information.
The speedometer is one of the most important of these instruments, allowing the driver to monitor vehicle speed and comply with road speed limits.
For the speedometer to remain readable during darkness or poor lighting conditions, its internal illumination system must function correctly.
The OE MATCH bulb socket 111957397/1 is designed to hold the appropriate illumination bulb securely within the speedometer assembly.
It also provides the electrical connection necessary for the bulb to illuminate when the instrument lighting circuit is switched on.
Although relatively small, the bulb holder plays an important role in the reliability of the dashboard lighting system.
If the socket becomes corroded, damaged or loose, the electrical connection may become unreliable.
This can lead to intermittent illumination, flickering or complete failure of the affected speedometer light.
Classic Porsche vehicles are particularly susceptible to age-related electrical connection problems.
After several decades of service, original bulb sockets may develop corrosion, oxidised terminals, weakened contacts or physical damage caused by previous maintenance.
Repeated bulb replacement can also wear the socket's retaining features, making it difficult to hold the bulb correctly.
Replacing a defective bulb holder with OE MATCH part number 111957397/1 helps restore secure bulb retention and reliable electrical contact.
This product is particularly suitable for Porsche 914 instrument repairs, dashboard illumination maintenance and classic vehicle restoration projects.
The replacement allows a damaged bulb socket to be renewed without unnecessarily replacing the complete speedometer assembly.
What This Product Does:
The speedometer bulb socket holds the dashboard illumination bulb and connects it to the vehicle's electrical system.
Its primary functions include:
- Holds the Speedometer Bulb: Keeps the correct illumination bulb securely positioned.
- Provides Electrical Contact: Connects the bulb to the dashboard lighting circuit.
- Supports Speedometer Illumination: Allows the instrument dial to be lit when the lighting circuit is active.
- Maintains Reliable Bulb Retention: Helps prevent the bulb from loosening during normal driving.
- Reduces Intermittent Lighting Faults: Provides a stable connection when correctly fitted.
- Supports Night-Time Visibility: Helps the driver read speedometer markings in darkness.
- Maintains Original Instrument Function: Restores the factory-style bulb mounting arrangement.
- Supports Instrument Restoration: Replaces corroded, damaged or missing original sockets.
- Allows Bulb Replacement: Provides a removable mounting point for servicing the illumination bulb.
- Preserves Dashboard Originality: Maintains a traditional bulb-based instrument lighting arrangement.
Symptoms Of Wear Or Failure:
Speedometer bulb sockets can deteriorate through age, heat, vibration, corrosion and repeated bulb replacement.
Common signs of failure include the following.
Typical symptoms:
- Speedometer remains dark when the instrument lighting is switched on.
- One illumination point fails while others operate normally.
- A new bulb does not resolve the fault.
- The affected lamp works intermittently.
- Speedometer light flickering while driving.
- Illumination cutting in and out over bumps.
- Lighting changing when the dashboard is disturbed.
- Bulb working only in certain positions.
- Intermittent loss of the affected instrument light.
- Visible corrosion.
- Green or white deposits near contacts.
- Darkened or oxidised terminals.
- Increased contact resistance.
- Intermittent or failed illumination.
Why Replacement Matters:
The speedometer bulb socket is a small but important part of the dashboard illumination system.
Replacing a damaged or corroded socket helps restore reliable lighting and supports clear instrument visibility.
- Restores Speedometer Illumination: Re-establishes bulb operation when the socket is the cause of failure.
- Improves Night-Time Readability: Helps drivers view speedometer markings in low-light conditions.
- Reduces Flickering: Replaces loose or deteriorated electrical contacts.
- Provides Secure Bulb Retention: Helps prevent the bulb moving within the instrument.
- Restores Electrical Continuity: Replaces damaged or corroded contact surfaces.
- Supports Dashboard Reliability: Helps maintain consistent instrument lighting.
- Preserves Classic Interior Appearance: Maintains the original-style bulb mounting arrangement.
- Suitable for Instrument Restoration: Replaces missing or damaged original components.
- Avoids Unnecessary Instrument Replacement: Allows targeted repair of the affected bulb holder.
- OE MATCH Replacement: Provides a classic Porsche-compatible alternative to an ageing original socket.
