942571 Bulb | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta bulb listed for 67 applications across AQ, B, BB, DP, SP and MS series units. It supersedes 841954, which was catalogued earlier as a bulb socket - so a search against the old number can return a socket listing rather than a bulb, and the description is worth checking before you accept it.

• Engine Family: AQ, B, BB, DP, SP, MS

⚙️ Key Features

• 67 applications across AQ, B, BB, DP, SP and MS units
• Supersedes 841954
• 841954 was catalogued earlier as a bulb socket

🔌 Function

Lights the instrument or indicator it sits behind, so the reading or warning can be seen.

⚠️ Common Signs of Failure

• Instrument or warning lamp dead while its neighbours still light
• Filament visibly broken or the glass blackened
• Light flickering or coming and going with vibration
• Base corroded, or the bulb loose and turning in its holder

🛠️ Service Notes

• Check the holder and its earth before condemning the bulb - a corroded holder kills bulbs repeatedly
• 943638 is the other bulb in this run and is tied to 873625 and 873624, so the two are not alternatives for each other
