A blinker fuse is any fuse that burns through a line of blinkers. Alternatively, it may refer to the 2c/3 period 18 fuse that burns cleanly through blinkers that are spaced four cells apart, shown to the right. This particular fuse can be combined with blinker puffer 1 to create various interesting patterns, such as moving sawtooth, slow puffer 1, and slow puffer 2.
Note
House alone, attached to a blinker wick with spacing 4, is a predecessor to the fuse shown to the right.
Other 2c/3 blinker fuses
There are two other well-known 2c/3 blinker fuses that act on blinkers that are orthogonally offset by four cells, both of which are shown below. They both burn cleanly and have period 6.[1]

c/2 fuse
The c/2 blinker fuse burns cleanly through blinkers that are orthogonally offset by an even number of cells and has period 2x spacing. HWSS burns clearly through output of both Blinker Puffers 1 and 2 and front part of Blinker ship 1.[2] It consists of a single heavyweight spaceship and is useful because it travels at the same speed as the known blinker puffers, allowing for the construction of arbitrary-length spaceships. Note that Coe ship's side spark can also be used in cleanup.

6c/13 fuse
The 6c/13 blinker fuse burns cleanly through blinkers that are orthogonally offset by six cells and has period 26.[2] It is most well-known for the role that it plays in blinker ship 1, where the fact that it burns at a rate slower than c/2 is taken advantage of to create a growing spaceship.
