…for night patrols (see the earlier post on Neighbourhood Watch).  After seeing the adverts for them on the web and on TV, we decided to buy a couple.  They are good.  The beam can be widened and narrowed, has different intensities and can give a slow or fast pulse (strobe) effect.   The ads say that the beam shone in a crim’s eyes will dazzle/disorientate them, and it probably will.
