To add a thing to the list: RF interference. I wanted to upgrade the super faint positional lights in my two garage openers, and I need to stay <= 10W, so I tried some LEDs. But they kill the 433 MHz remote signal, sadly. Tried 3 different brands, a couple of which don't actually fully turn off, or give off a loud hum to boot. The openers use rear car light bulbs, for some reason (BA15s).
