OVERVIEW
Genuine C5W bulb for the assigned interior lamp
N-901-200-01 is the Genuine VW/Audi C5W interior lamp bulb rated at 12 volts and 5 watts. Its festoon design uses contacts at both ends to fit the original compatible lamp holder.
Match the complete factory number, wattage and holder arrangement when replacing a failed interior bulb. A vehicle can use several bulb types throughout its cabin; the fitment below applies only to the original lighting position assigned this number.
Technical details
- Complete factory number: N-901-200-01.
- Factory specification: C5W; 12 V; 5 W.
- Design: incandescent festoon bulb with end contacts.
- Quantity supplied: one individual bulb.
The specified wattage matters to the lamp housing and electrical circuit. Do not substitute a higher-wattage bulb based only on apparent physical fit. This listing supplies the original bulb type rather than an LED conversion or complete lamp assembly.
Common reasons to replace
- The bulb no longer illuminates.
- The filament has failed.
- The glass envelope is damaged.
- The end contacts are damaged or heavily deteriorated.
- An incorrect bulb type was installed previously.
If a replacement bulb does not restore operation, inspect the holder contacts, lamp switch, electrical supply and relevant fuse according to the vehicle service information. A new bulb will not repair a damaged holder or wiring fault.
Vehicle fitment
Use only in the original C5W 12V5W holder assigned N90120001. Compare the removed bulb and verify the lighting position before ordering; this is not a claim that every interior lamp uses the same bulb.
| Vehicle | Model years | Engine | Configuration | Application restrictions |
|---|---|---|---|---|
| Audi Cabriolet | 1997 | 2.8L gasoline V6 | B4 convertible; Original C5W interior-lighting position | Only lamp position originally assigned N90120001 C5W 12V5W. Compare the removed bulb and holder. |
Installation guidance
Switch off the lamp and allow the old bulb to cool. Follow the factory trim and lens removal procedure, protect the lens retaining tabs and fit the correct bulb securely between the original contacts. Avoid bending or shorting the contacts.
Check lamp operation and ensure the lens and trim are correctly refitted. Investigate flickering or abnormal heat rather than increasing bulb wattage.
Ordering information
Supplied as one genuine incandescent bulb. The lamp housing, lens, switch and wiring are not included. Confirm the original part number and number of bulbs required.
