Can a 12V LED chip (the ones sold from China for $0.80 / pc) be installed directly into a car? Obviously the risk is from overvoltage since car batteries can supply anywhere from 11 volts when the car is off and the battery is powering multiple accessories (or one big one) to 14V when the alternator is running.
Obviously it will need a heat sink such as this:

I was just wondering if that would be enough to cool the LED to avoid premature failure due to heat.
Is that a good price for the heat sink? Anyone use scrap metal instead? I was just wondering if it's more cost effective to just buy a block aluminum ingot and use that instead of an aluminum heat sink.
