Oh great collective mind,

Does anyone have a guide to automotive light bulb codes and the wattages
etc.

I need a less powerful bulb for the aftermarket interior light I installed
and there are several that have the right base but I can't determine what
wattage they are.  1156 is the bulb that came with it.  It's very bright and
hot.  I tried a 67, I think it was, and it was even brighter.many of the
60's 80's and 90's seem to have the right base but I can't seem to find any
info on wattage or output, only that a certain bulb code is used for vanagon
taillights or Citroen back-up lights etc.

TIA
