The bulb is a 7309 F2 12v 35W, and none of the FLAPS around here have them and on their computer show as NLA, Ebay FLEEBAY had a few but like NOS for $25 a bulb!! I will sell these restored fog lights and buy some new cheap LED that will fit in the same spot before I sped $25-$30 for one single bulb!

question is , is there a LED that has same base to fit in there, or some other source that I am unaware of that these could be purchased at a reasonable price?

How about two shipped for $17

Or $11 shipped on Amazon

I will check that out thanks! I found AuthenticClassics.com- Mercedes , uses same ones , listed at $9.97 a piece, and another company Genesis lighting, sells a pack of 10 for $63. too so that's an option. -

So to clarify; there are no LED substitutes at this time?

With 35w equiv leds. Using the base of the original bulb and a little silicone to hold the led in place. As close to plug and play as it gets.Click to view attachment

they are unique but pretty cheap, plenty always in stock

Gonna bump this one instead of starting new...

Foglight is out, I pulled it and found I have, apparently the early foglights in my '74. To my incredible surprise, it uses these large ungainly Phillips 12227 bulbs. NAPA couldn't provide them so now I'm wondering if, after a couple years, there may be an LED solution that someone is aware of?

I have a single yellow foglight ("made in france") that uses a totally different bulb.

Current suggestions for replacements?

About 9W each; less than 1/3 the power of 35W bulb; twice as bright.

Man, you do nice work....

Highly recommended. Spoke's LED boards and Mark's yellow fog lenses. I've been meaning to post pictures, but haven't taken any yet.

Ok, I guess I have pictures. More impressive at night.

@jim_hoyland

If a yellow look is desired, it looks like the best way is to use white LEDs with yellow fog lenses.

I did a pair of "yellow" LED fogs for Jim but the color is very deep either yellow or amber, depending on your reference.

It seems the LED manufacturers mix the colors amber and yellow together interchangably. From wikipedia, they claim yellow has a dominant wavelength of roughly 570–590 nm

The "yellow" LEDs I used were OSRAM Yellow with wavelength of 590nm (583nm ~ 595nm).

Other manufacturers claim the same wavelengths for yellow and amber:
Everlight Amber 589nm (585nm ~ 593nm)
Everlight Yellow 589nm (585nm ~ 593nm)
Cree XPE2 Amber (585nm ~ 595nm)

Here's Jim's fogs and the color it produces. Very deep yellow/amber; not sure which it is.

Here's fogs with white LEDs behind yellow lenses. I think these are @Tbrown4x4 's. Notice how light the yellow looks compared to the "yellow" LEDs above.

I'm going to get a second opinion first; but I think the white LEDs with the yellow tinted film might be the way to go. I used the yellow film on my boxster and it's just right,
