Weapon light for tanfoglio witness

[jasonheimerm]

Ok  so  i will  be  using  my  10mm  i got  predominantly  for  a back  up while  bear  hunting and hiking .  I woud  like  to mount a  light.  The barska  light  i had  at home  is  for a picitiny  rail and  doesn't  fit  the  rail on my witness

Has  anyone  who  owns a  witness mounted  a  light? If  so  what light  works  well?
Thanks  in advance
