John.

Spot Hogg have a light on their web site that should fit your site I think they want $25 for it.

I picked up the light at a swap meet somewhere last year from memory I paid 50 cents for it.
I have it on velcro so I can take it off and put on my Patriot when needed.

It works real well it is a blue light I have it so it only lights up the 1st and 2nd pin for when I am hunting hogs at night

I am working on a Mag Light that takes 2 c cell batteries with a red lens to use as a stabilizer for when I am not in my spot which has the flood light
