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
This list does not include trivial fuses where a spaceship deletes or modifies stationary objects, or engineered fuses consisting of parts that can be trivially rearranged to get different speeds. Fuses where a spaceship deletes objects are known for c/6 orthogonal, c/4 diagonal and c/10 orthogonal.
Orthogonal
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.^{[1]}

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.^{[2]}

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.

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]}
