Additional Notes

The bulb size 70 is an ANSI-standardized miniature wedge type, classified under the T5 form factor, and operates at 12 volts with a power draw of 1.4 watts.
The T5 wedge base is a pinless design where the glass envelope itself forms the electrical contact, making it a common choice for low-wattage interior lighting applications such as sun visor illumination.
The Alfa Romeo Giulia uses the size 70 bulb for its sun visor across the 2021-2023 model years.
For the 2021-2022 model years, the size 70 fitment is specifically noted under the HID headlight configuration, indicating that trim or equipment level may be a relevant factor in confirming correct fitment.
