Lights?
LED's in our cars taillights is a big no no. You would have to use well over $300 worth of LED diodes, resistors, and drivers just to make them as bright as stock. Then there's the big problem, Heat. LED's put out a tremendous amount of heat, and require a heatsink.
Those cheap 1156, and 1157 led pnp bulbs are exactly that, CHEAP. They don't even put out 1/10th of the usable light of a traditional 1156 bulb.
