Just saw these on gizmodo today. While maybe not for the Eichler purist, the anodized aluminum would seem to blend well with a Modern/MCM theme. It's a shame they didn't use the Neutra font pack to create the numbers since that would have been a homerun!
Check them out here and let me know if anyone tries them out:
I saw these too and decided to give it a try. They look good, are built well, and easily installed, but the LEDs do not give off enough light at night. Plus, I placed them near an outside light that is left on in the evenings. The light from the light causes the solar numbers to not turn on! So now I'm looking at placing them in a new location.
