This is the mount I use that will fit a larger diameter torch. Should stay in place when on the road as long as things don't get too bouncy. Totally quick release and will swivel to aim. If the rubber ( slotted ) adjustable band is too small or too big to fit your torch you can always buy the appropriate sized O-ring and use that rather than the slotted band. Mine holds my 35mm Trustfire torch without problem but anything bigger might need a larger O-ring as the fit on mine is on the last slot and quite tight.
