Setup, Compatibility & Care
Setup: This is a direct replacement bulb. Ensure the vehicle is turned off and cool before attempting to replace the bulb. Consult your vehicle's owner's manual for the specific procedure to access and replace the indicator light bulb, as access points vary by make and model. Carefully insert the new bulb into the socket, ensuring it is seated correctly.
Compatibility: While Hella provides OE-quality parts and lists several OEM cross-references (AEBI: 12-97700611, BMW: 07 11 9 978 373, 71 19 9 978 373, 9 978 373), it is *essential* to verify fitment before purchasing. Check the bulb's socket type (W2.1x9.5), lamp type (W5W), voltage (12V), and wattage (5W) against your vehicle's specifications. Always check measurements and dimensions, as variations can exist even within the same vehicle model.
Care: Handle the glass portion of the bulb with a clean, lint-free cloth or gloves. Oils from bare skin can cause hot spots on the glass when the bulb is illuminated, potentially leading to premature failure. Once installed, no specific ongoing care is required beyond ensuring it functions correctly.
