\Yeoman,
Not familiar w/ the CVA light but I have a traditions that retails for $10.00 andI like it otherthan the light is green. Weird! It slides down the bore. It has a screw you rotate @ the back to turn it on. I just take a bread wrapper tie and double it and twist aroound the screw to make sure the light won't come on in my tool box...
