That resistor, however, is very small. It is not the same type needed to provide extra load to mimic the factory bulb... a resistor of that size would be much too large to fit in the bulb itself, which is why it cannot be integrated into the bulb. But you NEED the small resistor so that the LED chips will run on 12 volts.

Ours are designed for operation up to 18 volts, to prevent any failure with voltage surge which can happen in cheaper bulbs, which are often designed for use up to 14 volts.

Ok, thanks for the clarification.
