This is not an LED. It's a capless incandescent bulb mounted in a plastic bulb holder. You can probably buy them new from a Ford dealer but most likely cheaper from online shops/auction sites etc or buy a handful second hand from a scrapyard.
I guess they're designed to be easy to fit (1/4 or 1/8th? turn with two fingers) and more compact so there aren't huge bulb holders hanging out the back of the binnacle that will be knocked off when it is fitted in the factory...

have you checked with a ford dealer to see how much they are?
I found these new ones, anyway https://www.autobulb...nd-panel-bulbs/
there will be others elsewhere if you put the right description into a search engine. i have no idea the significance (or lack of it) regarding the colour of the base...

I managed to change all the bulbs for the speedo and rpm with leds. Just keeped the plastic base and mounted white smd's with small modifications. On ABS, Airbag and other indicators could work also spot leds. For gauges is needed a flood light, that's why I choose after many tests this kind of leds.
Passed more than 3 years since then and still working. Just test before fitting everyhting back. Because are leds the polarity matters.
The bulb that that I sacrificed in order to fit leds.
The leds used. I cutted them a little and fitted them into the original bulb base.
Other solutions can be used offcourse if you have spare bulbs to practice; I didn't.
The final result. Some darker areas but not so noticeable with the eye; more than 4 smd's on each bulb will help probably.
