I had someone explain to me exactly why it happens cause its a diode and not a resistor like a light bulb. Not that it matters, are the bulbs just plug and go? Id like to replace the lights on the rear view mirror of my car, map lights is what they are called? Mine are super dim and can hardly see anything with them on haha.


~EDIT~
did some quick reading, LEDs use P and N types of semiconductors, touching each other. In stupid terms, it looks like they wont conduct unless you apply enough electrical current, which makes sense as a semiconductor. thus to get them to flow and over come the natural resistance of the conductors, you need enough power, and if you drop below the threshold it just cuts out cause you lose the flow of electricity through the LED.

Thats how i read it anywho. I know there is more to it but, thats good enough for me for now haha.
