anyone know a good source for these bulbs? this is not the common H4 P43t base bulb in use now. this was used from 50's, 60's into early 70's in alot of european cars, and some bikes. Don't ask how or why it ended up in my HD, but it did. and the headlight housing it is in has been heavily modified, tothe point i am not willing to replace it just yet. I have heard rumors of there being an adapter to use the new P43t base bulbs in a socket designed for P45t bases, but no luck actually getting my hands on one. Looks like tomorrow evening the lathe may get fired up and machine one, but i really dread that. I attached a pic of an H$ with P45t base, so if anyone knows where to get them thanks in advance. Brian.
