I have a Strion 74001 s/n 44439 that I got about 7 or 8 years ago. If I had a short list of things to grab when running out of my house because it was on fire, this light would be on it. That the battery needs replacement is a no brainer. My question is this - the tailcap switch is acting a little funky. On its best effort full charge, depressing the switch works but if I back off the pressure just a tiny bit, the light goes dim. The same with the constant on - when I twist it on, it works but if I depress the tail switch just a little, the light goes dim. Is this related to the done battery or is it a mechanical issue? I have looked for a replacement switch but have not found one for the 74001, I have seen part number 747013 but also conflicting info on whether it will work properly on the 74001. Also the current 74001s are not the same as this one.
