It will drive your buddy nuts if that's a factor. Even if you don't look at them (which you will tend to do from time to time) every time you turn your head it looks like you are signaling for help.

I am quite sure that an alternate configuration -irrespective of its merits- will be rather offensive to those who are heavily invested in the status quo. Sorry to be so defensive about things, but it is frustrating to get a barrage of "Why would you do that?" replies to a pretty straight forward question.
It's rather like asking you what's the best way to take out my appendix. Your first response will be that I'm not trained and that in any event it's not a good idea to take out my own appendix.
I could respond that I didn't ask you for permission! I just want to know the best technique and which scalpel to use.
Otherwise, the real answer is to use whatever small light you have and attach it to your mask strap, forehead, or helmet. No real need for advice there.
That is an interesting analogy. What I was hoping for as a reply was something like "I use x strap on my small light to attach to my forehead (or mask strap), that I bought from x and am happy with this solution." I have seen some very high end solutions for this that are marketed to the professional recovery diver. These are quite a bit more than I want to invest. The OMS light is probably the best (within reasonable pricing) off the shelf light I can find for this application. And if I find the back-scatter to be too much of a nuisance, it can also be strapped to the back of the hand. I just have to get over my aversion to the somewhat non-standard battery size.
You are right Bryan, I do not advise performing your own appendectomy. But should you choose to you'll need....Just kidding.
