Need wattage of bulb

[Bob K <alfabob@domain.elided>]

I'm considering using a halogen map light bulb in the triple instrument
cluster of a '61 Giulietta Spider but don't want to do so if the wattage
is too high. There's no notation on the base or package and my usual
extensive web searches have failed to yield any information I can use. I
suspect it's a 10-watt bulb because the packaging contains a notation
"10-B47830-10," but admit that I'm grasping at straws here. The bulb in
question is a Wagner 47830 sold by Trak Auto as stock number BP47830.

Thanks in advance.
