HD light bulb part number conversion?

[Papi]

I have a 2004 Fatboy and I was wondering what bulb PN's IE sylvania etc..
So I can buy at my local auto parts store. I eventually want to swap to LED so I need to know the generic PN's

What bulbs? Single contacts should be 1156, double contacts would be 1157

As Jack said which bulbs are you interested in ? If you take the H-D pn's to sylvania's web site some bulbs they'll cross reference for you. Don't know about your '04 FB but my Heritage headlight is a H-4. If you go with LED's for signals & running lights you may have to add an equalizer which adds load, for the flasher to work properly. Try it first.
