Good idea, TITAN1833, though I don't trust my lights to thin nylon cords. Eventually, they break. I may have to give it a try with some braided Spectra thread I have. Well, I've got to braid it first, but I've got the thread somewhere.
I've been using a simple wrist lanyard setup myself, using some Spectra cord I bought from Berkeley Point a couple of years ago and some cord hardware from CountyComm.
Using about 17" of cord (perfect for my wrist/hand), a cord terminator and one slip lock, I ended up with this:
I simply pull the loop up under the light's clip and I'm ready to go.
As you can see, when I'm holding a light, there isn't any loose cord hanging down. Since I don't go around equipment where there is a risk of getting caught, I think it's relatively safe. A quick disconnect could be used in place of the terminator, for those with concerns of catching the cord in something.
If anyone wants to try this, don't put the terminator on until you've got just the right length of cord to fit your wrist. One thing I really like about this setup is that you can simply press the button with your thumb, letting the cord provide the resistance, instead of having to use your other fingers to provide it. For this technique to work, the length of the cord has to be just right. At the same time, I've used the same lanyard with several lights, and it seems to work great with any of them.
So far, I've been quite happy with this setup - my light isn't going anywhere. At first, I thought the cord might become frayed from sliding it under clips all the time. I've been using it regularly for several months without any obvious fraying. Spectra's some seriously tough stuff. I suspect that either the cord lock or the clip would fail before the cord did.
I hope you don't mind me posting this in your thread...
