í57 R60.
Previous owner installed this bulb and appropriate reflector. Bulb has no markings. Iím guessing that it is 6v because it works and during the Daytime, it is bright. Wasnít impressed during a night test. Although it may be a decades ahead upgrade.

Just wanted to get spare bulb. I call it an H4 base.

Anyone recognize this 6v bulb and know where they buy them ? (If it is 6v)


Photos wonít load correctly, but the bulb itself looks like every 60/55 black tipped H4 Iíve ever used.
