Blinker puffer 2 was found by David Bell in 1992 when he was trying to extend an x66. It produces blinkers that have the same spacing as those produced by blinker puffer 1.

The importance of this blinker puffer is that the engine which produces the blinker output is only period 4. The blinker row produced by the puffer can easily be ignited, and burns cleanly with a speed of 2c/3 (see blinker fuse). When the burning catches up to the engine, it causes a phase change in the puffer. This fact allows period 8 blinker puffers to be used to construct rakes of all periods that are large multiples of four.

Blinker puffer 2 and Hivenudger 2 are notable for the fact that they can survive burning catching up to the engine. With both of them, however, "bomb fuse" is quite dirty while both "house fuses" burn clearly. (In blinker fuse article, main image shows a period 18 House Fuse, second image shows the period 6 version, image 3 shows the "Bomb Fuse", named for its shape)
