1960s 1966 Deville Convertible BULB

Where can I get this type of Bulb.  It is the interior light on the underside of the dashboard on both sides. I would prefer to find an original one.

Does the bulb have a number on it?  If it doesn't have a number on it, look in your owner's manual to see what number it specifies for courtesy lamps (or whatever Cadillac calls the under-dash bulbs , then you can look online to see if you can find one, or a good substitution.  As a substitution, you could look at a NAPA # 6451-N bulb to see if the dimensions and wattage are the same.  Be careful of using a bulb that has more wattage than the OEM bulb, as a higher wattage will give off more heat and be bad for any lens that may cover it (if there is a lens).

Looks like a #212 bulb

This is for a courtesy light bulb.  Check the service manual also. Shape looks different but if wattage and size fits who cares its under the lens.
