Recently I was looking at some LED replacement bulbs for automotive lights, they look like this:
These bulbs are reversible, so you can plug them in either way and they still light up. Here's a quick schematic I drew after looking at one of them:
There appears two be two small components in transistor packages (SOT-23-3) that ensures the LED gets +12v no matter which way 12v is applied. How does this work? What are the two components that can do this? Thanks
