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.
House alone, attached to a blinker wick with spacing 4, is a predecessor to the fuse shown in the infobox (also known as a "house fuse").
Other blinker fuses
Orthogonal
2c/3 orthogonal
There are two other wellknown 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]}

4c/5 orthogonal
The 4c/5 fuse burns through alternating blinkers with the same spacing as the 2c/3 fuses. It was reported by Hugh Thompson in 1971.^{[2]}

c/2 orthogonal
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.^{[3]} 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 arbitrarylength spaceships. Note that Coe ship's side spark can also be used in cleanup.

6c/13 orthogonal
The 6c/13 blinker fuse burns cleanly through blinkers that are orthogonally offset by six cells and has period 26.^{[3]} It is most wellknown 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.
In January 2021, INoMed constructed an adjustable highperiod 3c/7 orthogonal puffer that repeatedly ignites this fuse.^{[4]}

8c/15 orthogonal
An 8c/15 orthogonal blinker fuse exists which burns through a row of alternating blinkers as follows:

8c/21 orthogonal
Another blinker fuse which runs on the traffic light, similarly to the 6c/13 fuse.

c/10 orthogonal
The c/10 blinker fuse burns cleanly through blinkers that are orthogonally offset. It consists of a single copperhead and can be used to create growing spaceships that grow very quickly.

Diagonal
There is a diagonal blinker fuse involving a Bheptomino reacting with a line of blinkers.

A wing can engage in a similar reaction, forming a glidereflective 2c/44 diagonal blinker fuse.^{[5]}
