I recently purchased a '63 Custom Electra VI Model E-48 and currently tearing it down to clean and recap. I want to change the two dial lamps with either LED or other incandescent style bulb. There seems to be a lot of sizes out there for all the different models and I want to make sure I get the right ones. The manual calls for PN 150441-3. Could you please provide me with some options on replacement bulbs? I appreciate the help!
