These will light red / green as the signal swings from a positive to negative voltage. Expect a very small drop in signal power! Light requires energy! However, in most applications, you will not notice any drop. The cables are slightly translucent and you can see the core of the cable. Material is a soft touch rubber that is presently flexible.
The colours are swapped for each end:
- Jack 1: red / green (+/-), Jack 2: green / red (+/-).
These dont just look pretty! They have practical advantages too!:
- Help seeing whats going on in the dark!
- Help diagnose signal flow.
