Not just a cool eurorack decoration but also a VERY handy tool to visually see what's happening with CV/outputt signals and figuring out interesting new patch options. I throw this in one half of a split cable with the other end in the destination so I can actually see what's going on in the signal!

Husband likes them.... the more flashing lights in the music studio the merrier

These are terrific! I got them initially to use instead of dummy cables for Maths. These are so informative. I highly recommend the dual color, as they will show you positive and negative voltages. To that end, they can be kind of like a quick meter of behavior of an output. I think they will also be fun to use for added lights on active unused outputs. They also pair quite nicely with stackable cables, so they can provide a visual aid to many signals! Customer service is top notch: helpful and outgoing. Quality build!

These are great, highly visible and easy to see triggers and LFOs. I have the blue (pos) and red (neg) ones so audio rate signals display purple. I originally received a slightly different type of LED than usual the seller went above and beyond to make it right and I'm very happy with the result!
