I did not know, previously, what the wattage rating was for a 194 bulb. After several searches, I finally found the answer.....3W.

As to your dilemna of how to restore the prisms, I would think a Dremel with various grades of polishing compound might be the way to go. Also for the reflectors, some have mentioned painting them with Testors white model paint or as referred to here, bright aluminum tape. I don't know how well the paint will hold up to the bulb heat or how easy it would be to get that aluminum tape to conform to the reflector. The trick might be to find the lightest weight, and probably the cheapest, exhaust tape you can find.

I am in the same quandry, as the PO installed the incorrect bulbs and melted the reflectors. I'm going to try the painting of the needles first with a flourescant paint color and then use a dremel to see if it will take care of some discoloration on the reflectors.
