The 3157LL bulb is the long-life version of the 3157k. Same bulb but will last longer.
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.
A 3157LL means 3157 Long Life, some stores carry it as 3357 bulb or a Heavy Duty 3157.the filament is stronger in the LL bulb.
