Additional Notes

The BMW Z3 uses the 6411 bulb for the dome light across the 1996-1998 model years.
The 6411 is an ANSI-standardized bulb designation, meaning it conforms to a defined North American specification used in both the United States and Canada.
The 6411 is a festoon-type bulb, which is a cylindrical lamp that mounts by pressing its end caps into spring clips rather than inserting into a socket.
The bulb measures 36mm in length, which is the critical fitment factor for festoon bulbs, as the housing clip spacing must match this figure for proper installation.
The 6411 uses an SV8.5 base, a designation that refers to the end cap style and width of the festoon bulb, indicating an 8.5mm cap width.
The electrical rating of the 6411 is 12 volts and 5 watts, consistent with standard low-draw automotive interior lighting.
