I also used some small bits of inner tube rubber glued to the inside area of the clamps to prevent scratching the flashlight and handlebars. Here is my 2AA Mag-Lite 3-watt LED light and two EMT conduit clamps ready to attach to the handlebar of a bike.
Here it is on my road bike.

I Used one plastic handlebar clamp with one EMT conduit clamp.
Plus,the handy spare bulb in the base of the Mag light!
How about using some 1 1/2" hanger and strapping on the 12" Mag light?
