The kx bulb has an extra pair of wire contacts (4 instead of 2) per side. This decreases the amount of current each contact has to handle and decreases the amount of heat build up on the socket. The regular 3057 or 3057K bulb can be used, but it will probably burn out a bit faster and can damage the socket over time.

Well. I work at NAPA and it called for a 3057kx which we naturally don't have in stock. But when the customer pulled the bulb out it was a 3157. which will fit in its place. It might be some sort of long life bulb. Just put a 3157 in there. that's what most brake lights are.
