Thanks DebW for the technical info - that answered my question exactly!

Yes - the cables would be deflected (thanks - I couldn't think of the appropriate word). They would be in effect rubbing on the rubber holder that the light attaches to. I can see how over time, the rubbing could make a channel in the holder. (I wouldn't care about the holder, but the effect on shifting would definitely annoy!). So I guess, unless I don't care about my shifting flaking out, I will not be glowing anytime soon

I kinda felt like the rubbing thing couldn't be a good thing, but, I guess I was just hoping that I was being over cautious

Now I'm off to pout about not glowing orange!
