Additional Notes

The 1003 bulb is the sole dome light bulb type listed for the VPG MV-1, covering the 2011-2012 model years.
The 1003 bulb follows the ANSI standard, which is the American National Standards Institute's classification system used across the United States and Canada to define bulb specifications uniformly.
This bulb operates on a 12-volt electrical system, consistent with standard automotive DC voltage.
The 1003 bulb carries a 21-watt power rating, which reflects a relatively modest draw typical of interior dome lighting applications.
It uses a single-filament design, meaning it serves one lighting function only, with no secondary filament for dimming or dual-intensity operation.
The base type is BA15s, a bayonet-style mount with a 15mm barrel and a single locating pin, which locks the bulb into its socket with a push-and-twist motion.
The BA15s base is not interchangeable with the BA15d base, which carries two offset pins rather than one, making pin count a critical factor in fitment.
