I was lookin for the same replacement and after an extensive search.
LEDLights.com product number 84758, P15D-30 is an exact replacement.I just installed them in my 38 Eight (120) and they work perfectly.

A problem often encountered when using modern bulbs is the alignment of the filament with the headlight lens. I experimented trying to use a H4 bulb in a Trippe headlight set (socket, reflector, lens) and was unable to get the light to focus correctly. It seems this is not a problem with the LED bulbs.

Apparently it does make a difference as outlined in a recent Jalopnik article.

Don, most interesting article. Thanks for the link. I did retrofit my 2016 Jeep Wrangler with a pair of LED headlights with lens heating elements. The Jeep uses the 7" round units. The new ones are the reflector type not the projector type. The difference between the LEDs and the original units was like day and night. The original Jeep halogen headlights were the worst I have ever had. The LEDs were expensive, but the night driving was made so much easier and safer. I opted for ones with the heated lens as the LEDs do not generate heat at the lens like conventional ones and north central New Mexico does get ice and snow. You don't want your headlights being covered by ice and snow on a dark winter night when it is snowing. JWL

I guess you will have problems finding anything Halogen or LED that will match the P30d base and socket of the original 2330 bulb. If not, you could come up with another pair of headlight buckets that would fit your exterior shell or housing and lens so you would not destroy the originals if the conversion did not work out. Removing the old socket and adapting a modern halogen socket and bulb to the bucket might be possible. Also, I haven't seen it myself, nor do I have any idea how to do it, but I read on a forum that it's also possible to use smart strip lights.

Just found these 2330 LED headlight bulbs online for my 1937 Super Eight. The links are listed below. Let us know if you buy one of these and how they work out!
