Essentially temperature rating. The K stands for "long life", the X for "high temperature". 3157KX is used especially in some Malibu front turn signals which double as daytime running lights. This means they run hot (in a small enclosure). For other applications the KX and LL can be used interchangeably, but in the above the KX lasts a lot longer than LL.
