This very day, less than 2 hours ago I was congratulating Honda for deciding to put incandescent bulbs next to the vanity mirrors. Of course, I've seen the threads with information about how to replace those incandescent bulbs with LEDs. However, Honda could have easily installed LEDs next to the vanity mirrors. It wasn't because the incandescent bulbs were cheaper than LEDs that Honda decided to use them. It was because those incandescent bulbs emit the spectrum of light the designers wanted to illuminate the faces reflected in those mirrors. Some on this forum claim they've found LEDs that emit light exactly like Honda's incandescent bulbs, but I doubt that's true. The fact that Honda chose these fragile, throwback bulbs for only this single application demonstrates a dedication to providing the best possible user experience for people riding in a Clarity. Insightman...out!
(Now watch, it will probably turn out that the only difference between the 2018 and 2019 Clarity PHEVs is the installation of LEDs next to the vanity mirrors.)
