VW / Audi 2-Pin 2.2mm 1156 Turn Signal Bulb Socket – OEM 1H0953123F / 1J0973722 / 8B0973822

Direct OEM-specification replacement for the 2-pin wire harness connector and bulb socket used on 1156 (BA15s) single-filament turn signal (indicator) bulbs across Volkswagen and Audi platforms. Cross-references VW / Audi OEM part numbers 1H0953123F, 1J0973722, and 8B0973822. Uses the 2.2mm contact series in black nylon and rubber housing — the standard turn signal bulb socket on VW Group PQ and B-platform vehicles.

What Problem Does This Connector Solve?

The 1156 turn signal bulb socket is located in the front or rear indicator housing, exposed to heat from the bulb and moisture ingress from the lighting assembly seal. The plastic locking tab fractures over time, allowing the socket to work loose from the bulb base and cause an intermittent or permanent indicator failure. Corrosion of the 2.2mm terminals inside the socket causes high resistance, which can cause the indicator to flash at the wrong rate (hyper-flash) or not illuminate at all — a roadworthiness violation.

Frequently Asked Questions

Q: My VW Golf indicator is not working and the bulb is fine — could it be the socket?
A: Yes. A corroded or loose 2-pin 1156 turn signal socket is a common cause of indicator failure on VW Group vehicles. The 2.2mm terminal corrodes over time, increasing resistance and causing hyper-flash or no illumination. Replace the socket (OEM 1H0953123F / 1J0973722) before replacing the flasher relay.

Q: Are terminals included?
A: Yes, terminals are included with all variants.
