Kael,

If you are willing to cross reference the information on these two links, I think you will find what you are looking for: in 6v and 12v; and, in CP and watts.

Bulb numbers and applications for mid 50s 6v & 12v bulbs. Use the MFG. NO. from this link and look for specs in the next link.

Cross-reference part numbers with information on wattage and CP.

Good luck,
Tim
